Embodiment Construction

[0014] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0015] With reference to the accompanying drawings, a special molten gold mixture for extracting gold from ores is synthesized by thermal reaction of sodium carbonate, urea, sodium bromide, sodium sulfide, sodium thiosulfate, yellow blood salt sodium, sodium fluoride, and sodium chloride. The mass ratio of each component is: sodium carbonate 0.26, urea 0.28, sodium bromide 0.03, sodium sulfide 0.06, sodium thiosulfate 0.2, yellow blood salt sodium 0.05, sodium fluoride 0.06, sodium chloride 0.06. It is made by heat reaction and concentration in a stirring furnace at a high temperature of 850 degrees.

[0016] The special molten gold mixture is cooled to normal temperature, crushed and packaged to become a product.

[0017] The exhaust gas produced by the production of special molten gold mixture is processed to produce ammonia fertilizer.

Abstract

The invention relates to a method for extracting gold from ores and a special gold-melting mixture, belonging to the technical field of gold production. The technical scheme is as follows: the special gold-melting mixture is synthesized by carrying out thermal reaction on the following components in parts by mass: 0.26 part of sodium carbonate, 0.28 part of urea, 0.03 part of sodium bromide, 0.06 part of sodium sulfide, 0.2 part of sodium thiosulfate, 0.05 part of sodium ferrocyanide, 0.06 part of sodium fluoride and 0.06 part of sodium chloride. The method comprises the following steps: mixing the components, and concentrating by carrying out thermal reaction in a sealed stirring furnace at the high temperature of 850 DEG C. The method can completely substitute the sodium cyanide gold extraction mode, is suitable for recovery and utilization of micro-series oxidation, half-oxidation, high-arsenic, high-sulfur and other polymetallic ores, tailings, slag tails and leach residues, is green and environment-friendly, lays stress on the environmental awareness, fully attaches importance to environmental protection, implements environmental protection in deed, and implements green mine and environment-friendly gold melting.

Description

technical field [0001] The invention relates to a method for extracting gold from ore and a special molten gold mixture, belonging to the technical field of gold production. Background technique [0002] At present, the gold production methods in the background technology are more common: flotation, gravity separation, amalgamation and carbon slurry process, etc.; , high-sulfur and polymetallic ore bodies have poor results. The traditional gold extraction process using sodium cyanide to extract gold from ore has the problems of difficult recovery and heavy pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for extracting gold from ore and a special molten gold mixture, which can completely replace the gold extraction method of sodium cyanide, and is suitable for micro-series oxidation, semi-oxidation, high arsenic, high sulfur and other polymetallic ore bodies and The recovery and utilization of tailings, tailings, a...
