Introduction
Molecular Formula: (C7H7O)2PSSH
Main Component: Dimethylol dithiophosphate
Properties: A black-brown liquid with an irritating odor and corrosive properties; density at 20℃ is 1.17-1.20 g/mL, slightly soluble in water.
Main Uses:
No. 25 Black Medicine has both collecting and frothing properties. It is an effective collector for the sulfide ores of lead, copper, silver, and activated sphalerite. It is commonly used in the priority flotation separation of lead and zinc, where it has very weak collecting power on pyrite and other sulfide iron ores in alkaline circuits. However, in neutral or acidic media, it is a strong non-selective collector for all sulfide ores. Product code: B2-01. Due to its slight solubility in water, it must be added in its original form to the adjustment tank or ball mill.
Specification:
• Content of dimethylol dithiophosphate: 60%-70%
