Silver is found in lead, zinc, gold and copper ore deposits. The most important oremineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.

Sliver flotation processing of advantages:
Silver flotation process mainly applied for the recovery of silver and associated metallic minerals, silver including two categories: one is silver &gold , the other is copper, lead and zinc associated.

Firstly, due to the thickness features of the silver particles to dissociate silver totally to improve the recovery rate. Secondly, use neutral or weak alkalinity pump as well as the sodium carbonate as regulators to improve the floatability of silver. Thirdly, sodium n-butyl xanthate and sodium butyl aerofloat are mix-used to enhance the collecting ability to the silver. Similar to other mineral processing methods, silver flotation process also need to prepare materials bef separation. That is to say, the ore should be grinded and classified to suit the flotation fineness. Hecngchang also adopts the multi-layer thickener to dewater in three stages, and exchange the cyaniding process of one leaching and one dewatering into two of each, which highly improving the recovery rate of the silver. Hengchang also use cyaniding to process Hydrogen-containing wastewater and to recover sodium cyanide, which proves to be a good method to solve the wastewater pollute. The alloy gold can adopt electrolyte equipment to dissociate silver, and get gold and silver ingot to improve the economic efficiency.
