the concentration of silver is greater than gold, the process that yields the most favourable economics for gold (and silver) recovery is Merrill Crowe cementation. In this process, the leachate is separated from the barren, leached ore, and gold and silver is precipitated from the pregnant liquor by reduction (cementation) on fine zinc powder

In ore stones, silver content is very low. In order to extract silver, it is necessary to crush and grind the ores and use dressing process to do pre-concentration or separate the silver from the ores. Gravity separation and flotation are commonly used in silver dressing. In the sand silver production, gravity separation has an important position. Flotation is the main dressing method applied

The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both

Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are

gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

The San Vicente plant utilizes a standard flotation process to produce a silver-zinc concentrate and a silver-lead concentrate. Ore passes through a jaw crusher at the plant, and then is fed into a semi-autogenous mill/ ball mill grinding circuit. Following the concentration process in the flotation circuit, the concentrates are thickened and dewatered in filter presses prior to shipping.

When the lithium chloride in the evaporation ponds reaches an optimum concentration, the solution is pumped to a recovery plant where extraction and filtering remove any unwanted boron or magnesium. It is then treated with sodium carbonate (soda ash), thereby precipitating lithium carbonate. The lithium carbonate is then filtered and dried. Excess residual brines are pumped back into the salar.

All that remained soon after the mines closed were piles of a byproduct from the silver
