How to reasonably collect lead zinc ore, how can there be a purchase of lead zinc ore?

The grade of lead-zinc ore refers to the amount of useful elements such as lead and zinc contained in the ore, and is usually expressed in percentages or grams. The grade of lead-zinc ore is an important factor affecting mining and economic benefits.

Generally speaking, different types of lead-zinc ore require different grades, but in general, lead-zinc ore with a grade of more than 8%-10% can be mined. Because when the grade is less than 8%, the mining cost will increase significantly, the mining volume is relatively small, and the mining benefit is very meager, and even the loss may occur.

Of course, the grade of lead-zinc ore is not the only factor that determines the value of the mine, but also needs to consider many factors such as the demand for municipal reform and plum farms, mining technology, and environmental protection requirements. In addition, after the ore is purified and processed, it can also improve the purity and value of the product, which can improve the economic efficiency.

Therefore, before the mining of lead-zinc ore, it is necessary to carry out rigorous exploration and evaluation of collapse, and comprehensively consider a variety of factors in order to make scientific and reasonable production decisions and ensure the sustainable development and economic benefits of the mine.

The grade of lead-zinc ore refers to the percentage of lead and zinc in ore containing Huaiyuan lead and zinc. The grade of different lead-zinc deposits will vary, but in general, lead-zinc ore must be of a certain grade to be of mined value. Generally speaking, the grade of lead-zinc ore must reach more than 3% to have economic value and can be considered for mining.

Of course, this also depends on a variety of factors such as the size, depth, and mining cost of lead-zinc deposits. Therefore, the specific situation of lead collapse needs to be analyzed and evaluated according to the actual situation of different areas and different core bending beds.

The lowest cut-off grade for primary lead tarser zinc ore is Pb; The minimum industrial grade is 1% 2% pb. The lowest yardyard cut-off grade of lead-zinc oxide ore is Pb; zn ；The lowest industrial grade of lead is Pb; zn 3%～6%。

Summary. There are many manufacturers of lead-zinc ore that have been acquired, and the key is to look at the distance from you. I inquired about the acquisition of lead-zinc mines, you can take a look.

Hello, at present, the mining of lead-zinc ore is basically the method of mine excavation and explosives blasting. Because the mine is not open pit and the space is limited, mining produces air and wastewater pollution, and workers suffer from occupational diseases (silicosis). Because of the use of multi-level mining, frequent drilling, finger blasting, prone to collapse, water permeability and other accidents.

At the same time, the use of blasting to advance the deep ore vein is limited, and the ore cannot be completely mined, resulting in a waste of resources. In addition, blasting mining is adopted, and there is no condition for ore testing and beneficiation, so the quarried stones (including waste rock) can only be transported to the beneficiation area in the whole town, which increases the cost. The ore part of explosive blasting is too large, and it is not lumpy, and the existing concentrator has to be crushed by a large crusher, ground into a slurry by a ball mill, transported to the beneficiation pool to add potion, and the lead and zinc are separated by refining.

The remaining waste residue and wastewater in the pond are sent to the fixed location of Yuda through the pipeline for stacking, and the land is re-acquired as a waste dumping site after the pile is full, which occupies a lot of space.

Hello, glad to answer for you. <>

The cost of lead-zinc ore beneficiation is 60 100 yuan a ton, lead-zinc ore is rich in metallic elements lead and zinc minerals, lead and zinc are widely used, with electrical industry, machinery industry, military industry, metallurgical industry, chemical industry, light industry and pharmaceutical industry and other fields. The cost of mineral processing mainly includes the cost of raw materials, equipment, site investment, labor costs, etc. The main expense is the cost of equipment.

Equipment is the top priority in our mineral processing field, which determines the quality and economic profitability of our products. The mineral processing equipment mainly includes: crusher, sand making machine, grinding stage trembling powder machine, screening equipment, conveying equipment, magnetic separator, flotation machine, etc.

The price of each kind of equipment here will be very different due to different types, different capacities, different models, different manufacturers, etc.

Summary. Hello dear, mining lead-zinc ore is risky. Here's why:

Its working environment is harsh, and there are many risk factors such as **, landslide, fall from height, object strike, mechanical and electrical injury, vehicle injury, etc. Objectively, there is the possibility of frequent **, and there are risk factors for mass death and injury.

Hello Qinliang sleepy, mining lead-zinc ore is risky. The reasons are as follows: its working environment is harsh, and there are many risk factors such as Bijian Bei, landslides, falls from heights, object strikes, mechanical and electrical injuries, and car regret injuries.

Objectively, there is the possibility of frequent **, and there are risk factors for mass death and injury.

The legal basis is: Article 16 of the Mineral Resources Law of the People's Republic of China Bu Xiaobu mining the following mineral resources, by the competent department of geology and mineral resources for examination and approval, and the issuance of mining licenses: (A) the national planning mining area and mineral resources in the mining area of great value to the national economy; (2) Mineral resources that can be mined outside the area specified in the preceding paragraph and have a large scale of mineral reserves; (3) Specific minerals for which the State provides for protective mining; (4) mineral resources in the territorial sea and other waters under the jurisdiction of China; (5) Other mineral auction resources specified in ***.

What is the specific situation here, it's easy to analyze here?

Legal analysis: Yes, but the following conditions need to be met: all new, Zheng renovation and expansion projects must strictly implement the environmental impact assessment system, and discharge pollutants with a permit (except for areas that have not yet implemented the pollutant discharge permit system), and discharge up to the standard.

Existing lead and zinc mining and smelting enterprises must implement mandatory cleaner production audits in accordance with the law. The environmental protection department supervises and inspects the implementation of environmental protection standards by existing lead and zinc smelting enterprises, regularly publishes a list of environmental protection production enterprises, and decides to deal with the enterprise that does not meet the emission standards or exceeds the total amount of pollutant discharge.
