factors affecting the flotation of gold in milling ores
ALTA Gold 2012 EDoc
The most significant item affecting the economics is the amenability of the ore to flotation where gold can be concentrated in a small mass pull and reduce size and cost of a plant (6). In addition the deportment/management of the acid produced in the oxidation process is a major factor.

Three Factors Affect the Classifying Effect of Spiral ...
There are mainly two factors that affect the classifying effect of the spiral classifier in the aspect of feeding, one is the mud content of feeding, another is the composition of particle size. The larger mud content or the finer particle sizes in the feed are, the stronger slurry viscosity is, and the slower settling speed of ore particles in the slurry will be, thus the particle size of overflow products is coarse.

Cyanide Leaching Of Gold
Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent the decomposition of cyanide in solution to form hydrogen cyanide gas.
