An ore is a mineral or combination of minerals from which a useful substance, such gold, can be extracted and marketed at a price that will recover the costs of mining and processing, and yield a profit (Encarta 2001). Mining in developing countries remains controversial since a huge impact on the cultural climate, the
Environmental Impact in the Gold Rush Era — Calisphere
The Gold Rush, positive for California in so many ways, had a devastating effect on the state's environment. Many of these problems were directly related to goldmining technology. The process of hydraulic mining, which became popular in the 1850s, caused irreparable environmental destruction. Two images show California's largest hydraulic mine ...

Gold Ore
Gold ores are classified "freemilling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory goldbearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of goldentrapment in different associated mineral phases before an .

Recovery of gold from refractory gold ores: Effect of ...
· The extraction of gold from refractory gold ores (RGOs) without side reactions is an extremely promising endeavor. However, most RGOs contain large amounts of sulfide, such as pyrite. Thus, investigation of the influence of sulfide on the gold leaching process is important to maximize the utilization of RGOs. In this work, the effects of pyrite on the stability of the .
Cyanide Use in Gold Mining
Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metalimpregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
