The design of the concentrator should be adapted to the characteristics of the ore, including the type of ore (such as quartz vein type, sulfide type, etc.), the form and distribution of gold in the ore (such as particle size, shape), the hardness, grindability, and magnetism, etc., these parts determine the required mineral processing method ...
Most gold ores, however, only require separation into two parts—the "concentrates," in which the precious metal is contained, and the " tailings," which are thrown away. The German system of coarse crushing, sizing by means of screens, and concentrating on jigs, is not, as a rule, applicable to gold ores proper, although much …
