how to process goldon a copperous ore

Silver Ore

The first stage of mining silver involves the crushing the silver ore to about 1-1.5in diameter so as to make the ore porous for the extraction process. Once the ore is crushed it is then mixed with lime (about 3-5 lb. per ton) to create a conducive alkaline conditions for the extractions. Get price

Ore enrichment

A mechanical process of copper ore enrichment is essential for effective smelting. The concentration level obtained at the enrichment stage makes the copper material fit for further processing at the smelter. This processing is required due to the fact that the copper ore deposits mined by KGHM in Poland contain, on average, only 1.52% of copper. The technology used by the KGHM Concetration Get price

How Gold Is Mined

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

How copper is made

The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Get price

How Gold Is Refined: A Step

Low-grade ore is relatively simple to process while high-grade ore is a more extensive and complicated process. Completing Off-Site Refining Once the initial processing is done on-site, the gold is transported to an off-site refinery to undergo further refining. Get price
