Abstract. Iron oxide coppergold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirtysix deposits in some well ...

A. Processing of Oxide Ore Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching and Solvent Extraction of Oxide Ore.

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods for the extraction of gold, by ...

The flotation concentrate is then dewatered and filtered to produce a filter cake that is sent to a copper smelter. Copper processing Ores, Refining, Smelting: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature.

Mining the ore : The first step requires the lead ore to be mined from the grounds. Heavy machinery is used to drill the rocks from deep tunnels or blast it with dynamite, breaking the ore into pieces. The ore is then shoveled onto loaders and trucks and hauled to a shaft. The miners dump the ore down the shaft, and from there it is hoisted to ...

Publisher Summary. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore that contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.
