Can coal gangue be used as organic fertilizer? Can cinders be used as fertilizer

OK. First of all, we must understand the coal gangue.

There is no organic matter in it. There is no organic matter that plants can use. Or if there are ingredients that can synthesize organic matter that plants can use at a low cost.

If not, then it is. As far as I know, coal gangue is a stone with a very low coal content mixed in the raw coal during coal mining. I don't remember what fertilizer was in it.

If only the trace elements in it are used.

and iron and the like, I don't know if the benefits are higher than the cost of production.

In other words, whether it is more cost-effective than using the same amount of active ingredient directly. However, it can improve the condition of soil compaction, and coal gangue contains humic acid.

Humic acid can be used to make organic fertilizer. The general organic fertilizer production does not need to use coal gangue, as long as the various elements meet the standard. However, some manufacturers refine the humic acid in the coal gangue to make humic acid organic fertilizer.

Coal gangue is a solid waste generated during the production and processing of coal.

The annual emissions are equivalent to about 10 percent of the coal output of the year, and more than 3 billion tons have been accumulated at present, covering an area of about 10,000 hectares, which is one of the largest industrial solid wastes emitted in China. China's coal system now emits nearly 100 million tons of coal gangue every year. Coal gangue is different due to different mines, and its main component content is also different, mainly containing humic acid.

Organic matter, silicon, potassium, iron, and many rare elements. At present, it is mainly used for power generation, production of building materials, mineral products, chemical products, road construction, etc., and its application in agriculture is less, and the effect is not very obvious. At present, the four major fields of agriculture, industry, environment and medicine are mainly coal gangue containing high-quality humic acid, and the humic acid content is generally more than 40%, and most of the coal gangue with low humic acid content is not rationally utilized.

The Administrative Measures for the Comprehensive Utilization of Coal Gangue, implemented in 2015, mentions that coal gangue is used for land reclamation. In this regard, the Shenyang Institute of Applied Ecology of the Chinese Academy of Sciences conducted research many years ago, and carried out soil improvement work in Chaoyang and Fushun, Liaoning Province, with remarkable results. After treatment, the salinization of the soil is reduced, the fertilizer use efficiency is increased by 8% to 15%, and the crop yield is increased by 8%.

Of course, it can be used as a compound fertilizer ingredient. In the production of compound fertilizer, appropriate ingredients will be added, most of these ingredients are mainly bentonite, etc., and the nutrients are single. The activated gangue can not only enrich the content of organic matter and humic acid in the compound fertilizer, but also provide a variety of medium and trace elements.

Coal gangue adsorbent. Coal gangue can also be called low-grade humic acid, which contains various functional groups and bridge bonds, has excellent adsorption, exchange and complexation properties, and has very light adsorption of pollutants in soil and atmosphere. The new fertilizer is the product of scientific and technological innovation, and it is one of the fertilizer products serving China's modern agriculture.

China's medium and low-yield fields are large, the organic matter is poor, the soil is acidified and alkalized, the sandstorm and salinization are serious, and the soil pollution is extensive. As a waste of the coal industry, coal gangue is also a very good fertilizer resource, which has huge reserves and low cost in China, and can be widely used in new fertilizers and land reclamation after treatment. While vigorously promoting high-quality humic acid, we can also activate coal gangue by biological, physical and chemical methods, and then make soil amendments for saline-alkali land, protected land and sandy land with different functions; It can be made into additives for compound fertilizers to reduce the development of bentonite and other resources; It can be made into environmentally friendly products such as biological fertilizers and pollutant adsorbents, which can be reasonably used in China's new fertilizers and environmentally friendly fertilizer products on a large scale, and contribute to the promotion of modern agriculture and environmental protection.

It can be used as a soil conditioner. Coal gangue.

After microbial activation, humic acid.

Active ingredients such as organic matter are significantly improved, which can promote the development of crop roots and the activity of beneficial microorganisms. To put it simply, it can help the soil release various nutrients that are conducive to plant absorption, control soil compaction, desertification, salinization, improve soil permeability, increase soil water and fertilizer retention capacity, reduce soil water evaporation, increase soil cation exchange capacity, and promote trace elements.

It is better absorbed by plant roots, which is conducive to the chelation of iron, magnesium, zinc and copper by plants, and reduces the absorption of Na ions in the soil by salt. , biofertilizer carriers. At present, bio-fertilizers are mainly based on individual bacteria or bio-organic fertilizers, and the carriers of bio-organic fertilizers are mainly livestock and poultry manure and straw, which provide organic matter during the period.

Coal gangue not only contains organic matter, but also contains a variety of medium and trace elements, which can enrich the function of biological fertilizer, and can also make reasonable use of the waste resources of the coal industry. <>

Summary. The amount of gangue used as a raw material for organic fertilizers varies by region, size, and market supply and demand. Generally speaking, in China, the ** of coal gangue is between 40 yuan and 100 yuan per ton.

However, the specific ** still needs to be determined according to the actual local situation. It should be noted that although coal gangue is cheap, its chemical composition is unstable, and it is not suitable for direct use as organic fertilizer, and it needs to be treated before it can be used.

The amount of gangue used as a raw material for organic fertilizers varies by region, size, and market supply and demand. Generally speaking, in China, the ** of coal gangue is between 40 yuan and 100 yuan per ton. However, the specific ** still needs to be determined according to the actual local situation.

It should be noted that although coal gangue is cheap and leakage, its chemical composition is unstable, and it is not suitable for direct use as organic fertilizer.

Guizhou coal gangue is only more than 600 kcal, how much is a ton.

If the coal gangue in Guigao Beizhou is only more than 600 kcal, it is lower than ordinary coal gangue, generally between 20 yuan and 50 yuan per ton. However, the specific ** should be determined according to the actual situation, because the ** will be affected by various factors, such as origin, reserves, market demand and so on. What needs to be injected is that due to the instability and uneven quality of coal gangue, some unqualified coal gangue may be mixed in it, so it is necessary to carefully choose the regular business and brand when buying coal gangue.

I have tens of thousands of tons to think **.

Now you can't sell a ton for 10.

If you have tens of thousands of tons of coal gangue and want to **, you can consider looking for a nearby coal gangue processing manufacturer or organic fertilizer manufacturer, or contact the local building materials market. However, due to the instability and uneven quality of coal gangue, it is recommended that you conduct quality testing before hitting the pure ** to ensure that the coal gangue meets the safety and environmental protection standards, so as to avoid adverse effects on human health and the environment. In addition, it should be emphasized that the unauthorized dumping of gangue will be severely punished by law, so please be sure to carry out ** and dispose of it legally and compliantly.

What is the minimum kcal in a cement plant.

The cement plant needs to be used, but I don't know what the minimum kcal of the cement plant is.

Generally speaking, the standard calorific value of China's cement industry is 5,300 to 5,800 kcal per kilogram, and the standard calorific value of coarse is 5,300 kcal to 5,800 kcal per ton. This means that the fuel in the cement plant needs to reach above this standard calorific value to meet the high temperature requirements of the cement production process. At the same time, the cement plant also needs to consider the quality of the coal, and adjust the width of the coal according to the quality of the coal to ensure the quality and efficiency of cement production.

If cinder is used as fertilizer, it will appear to be relatively inefficient, so it is generally not used as fertilizer, and cinder is more used as one of the cheap cultivation substrates, mixed with other cultivation substrates.

Because the cinder is calcined at high temperatures, the organic matter is burned out, and a small amount of lime is produced, making it alkaline. The phosphorus and potassium contained in it are a large number of elements necessary for plant growth, but the content varies depending on the coal-producing area.

As a substrate, due to the lack of organic matter, there is no buffer pH value of normal soil, and fertility is easy to be lost with water, so it needs to be used in conjunction with soil rich in organic matter.

No, because it contains less nitrogen, phosphorus and potassium, but more minerals, and other things should be added to make fertilizer.

Yes, cinders contain more potassium, magnesium and some trace elements.
