Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging the exact numbers of stages for each part should be decided by test work to reach the best recovery, and with the use of frothing agent and collecting agent, the copper concentrate
24/03/2016· Extraction of gold from ore revolves around smelting, not refining. I suggest joining the mining and prospecting forums to learn smelting or leaching techniques. Once you have made a good product from ore, then you can refine it to a pure metal. Mine gold. Buy silver. Fills the safe faster.

Gold CIL process carbon in leach is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99 .
A. Processing of Oxide Ore Oxide ores are generally processed using hydrometallurgy. This process uses aqueous water based solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.
This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes The calcine is heated to over 1200 °C with fluxes such as silica and limestone. The calcine melts and reacts with the fluxes. Some impurities form a slag such as FeO.SiO 2, which floats on the surface of the liquid like oil on water and is easily removed. Courtesy of

Gold extraction refers to the processes required to extract gold from its ores. This may requirebinationminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of
The mainposition of gangue minerals contained in this ore sample included quartz, muscovite, kaolinite and alunite. The relatively high copper extraction efficiencies were obtained over a 14 day period of the bioleaching experiments as a function of pH, pulp density and NaCl concentration. Therefore, the findings of this study provide the first information of bioleaching

Extracting gold from this type of ore is feasible for multi million dollarpanies, but almost impossible for the average person to do. Also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout. So a mine that produces some high grade ore will also process tons of ore with almost no value. To the naked eye, these
