it is essential to understand the history of mining to the modern life we enjoy today. mined materials were probably among the first materials traded. the egyptians and sumerians smelted gold and silver from ore 6,000 years ago. tin, mixed with copper, made bronze, the first alloy harder than its constituent metals.
pdf recently, worldwide production of gold from copper-gold ores has increased and most of the copper minerals readily react with cyanide to form prior to gold extraction and, then, adsorption of copper on activated.
pdf in recent years, copper-bearing gold ores have proved to be difficult to treat direct cyanide leaching of the ore with air resulted in a low extraction of gold the copper-rich gold ore sample was obtained from the sulphide-rich zones of
