The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage, pulp-solid-liquid ratio, leaching time, impurities in ore and amount of leaching aid and so on. This article will discuss how grinding fineness influence gold leaching process and its related problems and improvement methods.
The size of the product in a ball mill is influenced by several factors. Understanding these factors can help optimize the milling process for better results. 9 Key Factors Influencing Product Size in Ball Mills 1. Residence Time. The longer the material stays in the mill chamber, the more time it has to be ground, leading to smaller particle ...
The Factors Influence Grinding Fineness of Ball Mill. Factors affecting the grinding fineness are: ore hardness, crushing particle size, grizzly sieve, to the ore size, mill type, number of balls, ball size ratio, ball mill liner wear, ball speed, classifier speed, grading machine spindle lifting height, grader blade wear, classifier overflow height, lower …

Generally speaking, the fineness of grinding is related to the relation of inlay of ore, and the fineness of different inlay shape and fineness of ore have influence on the fineness of grinding. Take a gold mine as an example, the natural gold of this gold mine has a relatively fine particle size, and it becomes micrograined gold, 0.037~0.01mm ...
Five factors affecting the grinding fineness of the mill: 1. Raw ore hardness. ... The ball miller must supervise the crushing system. If the particle size of the mill is changed during the production, it must be reflected to the crushing workshop immediately. The final requirement is that the finer the particle size, the finer the better.
