The Study Of The Selection Of Lead-Copper Concentrate By The Sulfite Method

Currently, sulfoxide methods are of greatest interest for the practice of separation of lead-copper concentrates. The selection processes based on the use of sulfoxides such as sulfuric acid, sulfite salts, etc. should be included in this subgroup.d. Typically, these reagents are used in combination with other depressors [3]. The main advantage of sulfoxide methods is the lack of dissolution of noble metals and higher efficiency compared to many known methods. The subgroup under consideration includes a method using sodium sulfite, iron vitriol and sulfuric acid for halenite depression Currently, about thirty methods of flotation separation of lead-copper concentrates are known.
