Why can some quartz stones coexist with gold?

First of all, the statement that "quartz ore is often accompanied by gold mines" is not rigorous.

The main component of quartz is silicon, and the freezing point of gold is relatively low. They tend to solidify at the end of the rock formation process and are squeezed into the cracks of the existing rock to form veins. Quartz of medium and low temperature hydrothermal origin is often associated with sulfides such as gold and silver.

The ore-forming fluids are together.

Therefore, the most obvious prospecting sign for quartz vein-type gold deposits is quartz vein, as well as other pyrite.

and so on, which often produces bright gold, and the big one is the dog's head gold.

Gold placers are often found in the surrounding ditches of these gold mines.

Selectivity of classification characteristics and beneficiation methods.

1) More than 90% of quartz-containing gold-bearing ore ore is quartz, and the metal mineral is natural gold, almost no other sulfides, and the gold grains are mostly coarse-grained. Coarse grains can be used by gravity separation or amalgamation**; Fine-grained mostly uses the whole mud cyanidation method.

2) The symbiotic relationship between gold and sulfides is close, and the metal minerals are dominated by pyrite. Sulfide content 1 5%; Gangue is dominated by quartz; More than 60% of natural gold is symbiotic with sulfides. Gold is dominated by medium and fine grains.

It is an easy-to-beneficiate ore, mainly cyanide method and flotation method, and the cyanidation process of flotation fine sand is commonly used.

3) The symbiosis between gold and quartz is closely related, and there are few metal sulfides, and more than 70% of gold is symbiotic with gangue minerals such as quartz. Generally, the particle size is finer. Cyanidation and flotation methods are the main methods. Amalgamation and gravity separation assisted **coarse-grained gold.

4) The mineral composition of pyrite gold-bearing quartz vein ore is the same as (2), the main difference is that the sulfide content accounts for 5 15%; 75 99% gold is symbiotic with pyrite. Very easy flotation, the best rate of gold.

It reaches more than 95%, but the grade of gold in flotation concentrate is low.

5) The main metal mineral partially oxidized is limonite, followed by a small amount of pyrite. Gangue is quartz. Gold is found in mineral fissures. Characterized by iron hydroxide.

Contains gold. Mineral processing is mainly gravity separation (amalgamation) + cyanidation method. Flotation can also be used.

6) All oxidized without sulfides. Kim Dae.

Some of them are found in gangue minerals and weathered metal oxides.

Among the residual particles, the ore contains argillaceous. Coarse-grained gold is mixed with mercury and gravity separation**. Sludge stirring cyanidation, ore sand seepage cyanidation.

To sum up, it is no problem to say that quartz vein gold ore is closely related to quartz, but it cannot be said that quartz ore can produce gold, but it is only vein quartz type ore, and the probability is very small.

Because they are all similar substances, they can be symbiotic.

Because they have a lot of commonalities, they have been assimilated over time.

Because they have been assimilated by gold, they have some of the properties of gold.

The main thing is that quartz stone and gold have the same physical properties.

This is the principle of mutual dependence, mutual support.

Because quartz can be assimilated by gold.

This may be because of the same characteristics.

The properties of these two substances are similar.

Because it has similar characteristics as **.

Because they can accommodate each other very well.

Quartz is a mineral resource with very stable physical and chemical properties, and gold ore veins are mineral components that can only be produced under very unstable conditions, so under normal conditions, quartz stone will not be associated with gold ore veins.

Quartz stone is a kind of abbreviation for the plate produced by the current quartz stone plate manufacturer, because the main component of the plate quartz content is as high as 93 or more, so it is called quartz stone, and the purer general quartz is widely used as glass raw materials, grinding materials, siliceous refractory materials, etc. Impure quartz is an important building material, so it is impossible for stone miles to contain gold.

No, it won't! It is impossible for iron ore quartz to be mixed with gold ore.

There are naturally occurring gold telluride minerals, and small amounts of gold are also present in sulphide ores of iron, aluminum, and copper.

Yes, and it's Mingjin. We have one in our hometown.

**Medium white is whether quartz stone is good or not.

Speaking of quartz, which is called silica in chemistry, it is often seen in our lives, because on the surface of our earth, the distribution of this thing is relatively wide, but quartz is also divided into three, six, nine and so on, and not what kind of quartz stone can be accompanied by **. This is something that has evolved through geology.

Quartz is a relatively large mineral because of its hard texture, so it is also relatively versatile. The production of this mineral, which has a wide range of uses, will have some accompanying substances, such as gold ore. The physical properties of quartz are relatively stable, and the chemical properties are also relatively stable, just like the structure of our carbon, which is not prone to chemical and physical reactions.

Generally, where there are quartz mines, there are not necessarily gold mines, but where there are gold mines, there are generally quartz mines. In the past, there was a profession called gold diggers, they were panning for gold in fine sand, and the claimed component of sand was also silica, that is, quartz, because the texture of quartz and gold is relatively hard, and the changes in high temperature and high pressure experienced by the two of them are almost similar, and they are also born together.

There are many types of gold mines, among which there is a kind of gold ore called hydrothermal gold mine, and quartz is also a hydrothermal mineral, the formation of these two minerals is inseparable from a substance, called hydrothermal fluid.

Hydrothermal fluid is a high-temperature liquid that uses water as a carrier and contains a variety of substances.

Hydrothermal fluids can be dissolved**. When a volcano erupts, it spews hot magma into the gold mines, followed by hydrothermal fluids and quartz.

The hot liquid dissolves **, so that ** and quartz stay in the same space, which is the initial combination of ** and quartz.

Volcanic eruptions will also have a day to stop, so after the volcanic eruption stops, no more magma is spewed, the temperature of the mine gradually decreases, and after the temperature decreases, the ** and quartz in the hydrothermal fluid gradually crystallize because of the temperature decrease, and finally combine together.

This also explains why quartz and ** always go hand in hand.

However, only when the gold mine is a hydrothermal gold mine, will it be accompanied by ** and quartz.
