Extracting Gold HowStuffWorksRemoving the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore tocopper extraction and purifiion chemguideThe method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silie, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of

It is the only metal, forUsing Borax Flux to Refine Gold MGS Precious Metals BlogThe MGS Precious Metals Blog. With some borax, heat, and a little knowhow, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.
Copper extraction WikipediaCopper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be History&ensp·&enspRapid, Selective Extraction of Trace Amounts of Gold from With the everincreasing production of electronics, there is an ensuing need for gold extraction from sources other than mines. Currently, there are no technologies reported to date that can effectively and selectively concentrate ultratrace amounts of gold from liquid sources. Here, we provide a blueprint for the design of several highly porous composites made up of a metal–organic
