Abstract

The invention discloses a copper gold silver ore flotation collecting agent and a flotation method, belongs to the technical field of ore flotation, and solves the prominent problems of low copper gold silver ore beneficiation efficiency, high cost and the like. The copper gold silver ore flotation collecting agent ester-205 is prepared from the following raw materials: 30 to 40 parts of N,N-diethyl dithiocarbamate, 20 to 25 parts of diisopropyl dithiophosphate, 10 to 15 parts of black powder acid, 20 to 30 parts of terpenic oil and 2 to 5 parts of ethyl alcohol. The flotation method comprises the following steps: preparation of flotation pulp, flotation preparation and copper gold silver ore flotation. According to the copper gold silver ore flotation collecting agent and the flotation method, multiple circulation times and metal loss of target metal ores in a flotation process are effectively avoided, so that the trunk flotation process is shortened, and the investment and operation cost is reduced; the collecting agent ester-205 is high in collecting capacity; the flotation speed is increased; the copper gold silver recycling rate is increased; the number of the scavenging times is reduced; and the types and the use amounts of flotation agents are reduced.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation, and in particular relates to a copper-gold-silver ore flotation collector and a flotation method. technical background [0002] Most copper sulfide ores are associated with precious metals such as gold and silver, and the comprehensive recycling of resources is of great value. The recovery of associated gold and silver minerals from non-ferrous metal mineral resources has played an important role in gold and silver production. The traditional beneficiation method of copper sulfide gold and silver ore is mainly based on flotation, and the flotation collectors mainly include xanthate, black medicine, etc. Although the recovery of copper, gold and silver minerals can also be achieved, patent 103691569 announced a high The flotation method of sulfur-containing gold-copper ore, but the recovery rate of copper and associated gold and silver is low, the beneficiation efficiency is low, and the...
