Abstract

The invention relates to the field of industrial gold extraction, in particular to an environment-friendly gold extraction agent and a production technique thereof. The gold extraction comprises, by weight, 25-35 parts of urea, 15-25 parts of sodium hydroxide, 10-20 parts of sodium carbonate, 5-15 parts of sodium ferrocyanide, 10-20 parts of sodium oxide and 5-15 parts of thiosulfate. The production technique comprises the following steps: the above components are uniformly mixed and are subjected to a reaction at 600-850 DEG C for 1-3 hours, then are melted and cooled to room temperature, and finally are crushed to obtain a finished product. The environment-friendly gold extraction agent and the production technique thereof have the advantages that the gold extraction process is safe, environment-friendly and efficient, so that the problem that a great hidden danger of production safety exists for a long time in the gold extraction process is solved, the technique is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of industrial gold extraction, in particular to an environment-friendly gold extraction agent and a production process thereof. Background technique [0002] At present, in the production of gold and silver mining at home and abroad, the dressing and smelting process of cyanide method is widely used. Since sodium cyanide is a highly toxic and dangerous chemical, there is a high risk in the production process, and in the later period of long-distance freight, storage In the use link, a considerable part of material and financial resources must be invested, and it will inevitably cause irreparable harm to humans, animals, and the environment, especially major personal safety accidents continue to occur. Contents of the invention [0003] The purpose of the present invention is to overcome the major hidden dangers of production safety in the prior art, the serious waste of manpower, material resources and financial res...
