Problems solved by technology

Commonly used collectors include thiourethane collectors, xanthate collectors, and black drug collectors. Conventional collectors are better at recovering copper sulfide minerals, and they are better at recovering copper, copper oxide, etc. The mineral recovery effect is poor, and the loss of gold and silver in the tailings is relatively high

Abstract

The invention discloses a pyrometallurgy copper smelting slag copper-gold efficient collecting agent and application thereof. The formulation of the efficient collecting agent comprises 3%-6% of xanthic acid collecting agent, 15%-25% of dimethyl sulfoxide, 5%-10% of O-alkyl-N-alkyl thiocarbamate, 5%-10% of N, N-diethyl dithiocarbamate propionitrile ester, 20%-30% of N-allyl-O-isobutyl thioamino acid formate and 25%-40% of terpenic oil. Aiming at the properties of the smelting slag, the synergistic effect of different collecting agents is fully utilized. Recovery of sulfide minerals in the smelting slag is enhanced, particularly, the recovery effect of precious metal gold and silver is obvious, and efficient recovery of useful minerals in the smelting slag can be achieved. The novel reagentis good in fluidity, stable in property, stable in component, wide in raw material source, low in price and capable of being directly added during use so that the production index of the slag separation plant can be improved, and the reagent cost of mineral separation can be reduced and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the technical field of beneficiation of non-ferrous metal minerals, in particular to a high-efficiency collector of copper and gold for pyrometallurgy copper smelting slag and its application. Background technique [0002] Copper slag is a kind of "artificial ore". Its physical composition, physical and chemical properties, symbiotic relationship between minerals and the size of intercalation between minerals are related to factors such as smelting equipment, technical conditions and cooling methods. Copper slag is usually in the form of black dense block, brittle, friable and difficult to grind are its main properties. The main useful mineral of copper in the slag is copper sulfide ore, followed by a small amount of oxidized copper ore and metallic matte. Due to the rapid crystallization, most of the copper particles contained in the copper slag are in a finely dispersed colloidal state; Mainly fayalite (2FeO SiO 2 ) morphol...
