What is the commonly used collector for mineral dressing
In addition to coal, graphite, the sulfur in the nature, talc and molybdenite surface hydrophobic mineral particles, has a natural flotability of most minerals are hydrophilic, gold content is the same. A potion can change the hydrophilic properties of the mineral particles and produce hydrophobic water, which is commonly referred to as an adduction agent. The collector is usually a polar catcher and non-polar catcher.
Polar traps consist of polar groups and non-polar groups that act on the surface of the mineral particles. When this kind of collector adsorption on ore grain surface, its molecules, or ions are arranged orientation, polar groups toward the surface, mineral grain nonpolar groups outwards to form hydrophobic film, so that the ore deposit has flotability.
And copper, lead, zinc, iron sulfide minerals associated gold, often used in the flotation of organic sulfur compounds as pu collectors. For example, alkyl (b, c, d, e, etc.) disulfide generation of sodium carbonate (potassium), also called xanthate salt, commonly known as yellow pills. For example, NaS2C, OCH2, CH3, in the flotation of gold and polymetallic ores, use ethyl and butyl yellow. Alkyl dithiophosphate or its salts, such as (RO) 2PSSH, in the form of R for alkyl, commonly known as the black drug.
