Silver ore mainly refers to the ore containing the main metal silver and other metal impurities, there are more than 200 kinds of, of which silver is the main element of silver minerals and silver-bearing minerals have more than 60 kinds, but has important economic value as the main raw material for silver production has 12 kinds. Silver ore belongs to the sulfide minerals, colour black or grey, no metallic luster, opaque, silver is a copper-type ions, pro-sulphur, strong polarization ability. In nature, often in the form of natural silver, sulphide, sulphur salts and so on.

Silver ore beneficiation methods often take flotation process, the specific choice of flotation process is usually based on the nature of the gold and silver ores and the specifications of the product to determine the common ways are mainly flotation + flotation concentrate cyanide, flotation + concentrate roasting + roasted sand cyanide, flotation + flotation concentrate fire treatment, flotation + flotation tailings or mid-range ore cyanide + flotation concentrate cyanidation in situ roasted cyanide, raw ore cyanide + cyanide tailings flotation, etc., and so on. These are based on the user's specific mineral properties and production requirements to the actual choice of flotation process. More specific can consult Henan Red Star Machine, here not only has the flotation machine and other equipment, but also design production line process.

Silver ore flotation process enhancement

1, for the silver mineral embedded particle size of coarse and fine characteristics, as far as possible to make the silver minerals fully dissociated, improve the silver recovery rate;

2、Select neutral or weakly alkaline flotation pulp alkalinity and choose sodium carbonate as the adjusting agent of flotation pulp to improve the silver flotation;

3、With the use of yellow and black drugs, to enhance the silver trapping capacity.
