introduction of gold

Gold is usually found in a pure state nevertheless,it may also be extracted from silver, copper, lead and zinc. Seawater also can include gold, but in insufficient quantities to be profitably extracted-up to one-fortieth (1/40) of a grain of gold per ton of water. Gold is typically identified in two types of deposits: lode (vein) or placer deposits. It truly is usually extracted from lode deposits by drilling or blasting whereas placer deposits demand hydraulic mining, dredging, or energy shoveling. When extracted the gold ore is pulverized to prepare it for refining.

gold ores type

Gold ores are typically classified by the metallurgist into two main categories: freemilling and refractory ores. Normally, free-milling ores are defined as those where over 90% of gold is often recovered by standard cyanide leaching. Refractory ores are defined as those that give low gold recoveries or give acceptable gold recoveries only together with the use of substantially far more reagents or extra complicated pre-treatment processes.

gold crushing machine processing

Blending from different stockpiles with respect to grade and hardness, in the point of feeding into the crusher, is practiced for optimum grinding and recovery traits. Run of mine ore is crushed to -110 mm by a 375 kW Jaw crusher. Major crushed item is fed to a 7ft, 450 kW gold crusher after scalping with the -35 mm material.Secondary crusher operates in closed circuit having a 35 mm aperture screen. The crushing circuit includes a multi-function style, which enables by passing of secondary crushing circuit or operating secondary crushing circuit in closed or open circuit. Final product from the crushing circuit is stockpiled just before feeding into a 7.two m SAG mill. When the primary stockpile is complete, secondary crushed solution may be diverted to an emergency stockpile.
