Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

Definitions. "Pulp," in flotation terminology, is a freely-flowing mixture of powdered ore and water. "Pulp density," when the phrase is applied properly, indicates the specific gravity of the pulp. "Percentage of solids" means the ratio, expressed as a percentage, of the weight of the solids in a pulp to the total weight of pulp.

Gravity concentration is a mineral processing technique used to separate minerals based on their specific gravity or density. This is a physical separation process that uses differences in mineral density to separate them. It takes advantage of the fact that dense minerals settle faster than lighter minerals when placed in liquid or water.

In mineral processing, ores must go through a number of different operations to obtain the final products. Thus, mineral processing involves four major steps or stages: (1) comminution or size reduction, (2) size separation, (3) concentration or beneficiation by taking advantage of physical properties, and (4) dewatering.
