May 01 2018· Concentration of gold to economic ore grades has been highly episodic through Earth's history with different sedimentary magmatic and hydrothermal processes having operated as principal driving forces at different times Comparison of the various types of gold deposits their secular and spatial distribution and the amounts of gold contained

The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue Complications are often introduced by the fact that various base minerals must be separated from one another an ore being subdivided into several products Most gold ores however only require separation into two parts—the “concentrates ” in which the precious metal is

The treatment process of a low grade refractory gold ore containing sulfide minerals and carbonaceous matters was studied in this work The gold extraction of this ore by all sliming cyanidation was only 11 75 Hence a pretreatment was necessary In this paper a flotation preoxidation cyanide leaching process was developed

The common definition of “refractory” gold ores are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite

The mineralogy of gold bearing ores plays a vital role in predicting the behavior of minerals and ores during processing To evaluate the relative contributions of gold in gold bearing ores the

Due to the inherently low concentration of gold in ore and the relatively long retention time required for gold to dissolve gold cyanide leaching reactors are usually very large with a size of up to 5000 m3 For the same reasons the solids content in tank leaching is kept at a high level around 40 wt Currently a typical agitator

Instead of finding the concentration per 100 parts like the percentage ppm finds concentration out of one million parts This unit is used to represent metals that often occur in smaller concentrations A gold ore with a 2 ppm ore grade would have 2 pounds of gold for every 1 000 000 pounds of ore
