In order to insure contact between the gold and cyanide solution, the ore must be ground very finely. It may not be feasible to grind the entire ore to the necessary degree of fineness. In such cases the ore may be ground sufficiently fine to liberate the gold-bearing mineral which is then floated or concentrated by some other means.

Tin Ore Assay.—The ore to be smelted or assayed should be concentrated to say not less than 50 per cent, of metallic tin; though to obtain satisfactory results it should be brought nearer 70 per cent., as with ore containing less than 40 to 50 per cent, of metal there will be a considerable loss both in the assaying and in the smelting.
Tin ore is a type of mineral ore that contains tin, a soft, malleable, silvery-white metal. Tin is commonly used in various applications, including as a coating for other metals to prevent corrosion, in the production of solders, as a component in electronics, and in the manufacturing of tin cans. Tin ore is typically found in rocks and minerals, often in association …

Following the fine grinding of gold ore, intensive measures are taken to achieve all-slime gold cip plant according to the characteristics of gold and sulfide minerals in gold ore. In addition, sulfide minerals are soluble in cyanide solution to a certain extent, and the resulting soluble sulfide will hamper cyanide leaching.

The presence of glycine leads to low cyanide consumption, high metal recovery, zero or very low free cyanide during leaching, and copper complexed primarily with glycine rather than cyanide in tailing solutions (Oraby et al., 2017). Thus, co-intensifying systems with ammonia or glycine were developed to reduce the adverse effects caused by copper.
