Gold processing These images are derived from two properties of gold, its colour and its chemical stability. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed .. effect on rainforest.
Gold is extracted from its ores by mechanical means and separated from other metals by chemical processes, notably the cyanide process, the amalgamation process, and the chlorination process (in this the ore is oxidized and chlorinated and the gold precipitated with hydrogen sulfide). It also occurs in compounds, notably telluride minerals.
Specimens of gold which is a form of gold with a mineral carrier or quartz and has a size of metallic ore which is almost the same as free gold. Where the gold grains are visible with the naked eye either intergrown with gangue in primary deposits or as a loose item in secondary deposits.
Lode deposits are the result of magna, high temperature and high pressure that thrust liquid gold up from Earth's crust. Cooling water seeping through the metamorphic rocks hardens the gold, resulting in ore deposits that run through sedimentary rocks as veins.
