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 ...
Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput. This is essential for driving the overall efficiency of the operation because the process of grinding and crushing ore known as comminution is on average the highest energy

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.
An arrastra, also known as a Mexican Rastra, was a primitive method used by early miners to process gold and silver ores. It was introduced to the new world by the Spanish in the 1500s. They were used throughout the world, often at remote locations where other processing methods were not feasible.
Ore is stockpiled 1 at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added 2 to raise the pH of the ore. Following crushing through a jaw crusher 3, the ore is fed into the semi autogenous grinding SAG mill 4 along with water and steel balls.
