Abstract

The invention discloses a gold ore low-toxicity efficient mineral separation addition agent and a preparing method of the agent. The gold ore low-toxicity efficient mineral separation addition agent comprises, by weight, 40 parts to 60 parts of thiourea, 20 parts to 40 parts of potassium ferrocyanide, 10 parts to 15 parts of sodium tripolyphosphate, 8 parts to 15 parts of ammonium iodide, 10 parts to 15 parts of ammonium persulfate, 8 parts to 12 parts of sodium peroxide, 20 parts to 40 parts of sodium carbonate, 5 parts to 10 parts of sodium hydroxide and 4 parts to 8 parts of sodium dodecyl sulfate. The gold ore low-toxicity efficient mineral separation addition agent has the advantages of being low in toxicity, environment-friendly, low in production cost, simple in preparing technology, high in gold recycling rate, wide in raw material source and the like, and has the good social benefits, the ecological benefits and the economic benefits.

Description

technical field [0001] The invention relates to a precious metal beneficiation agent, in particular to a gold ore beneficiation aid with low toxicity and high efficiency and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the demand for gold is rapidly expanding. Only by constantly looking for, developing and utilizing new gold mineral resources can the needs of today's society be met. The existing gold ore beneficiation methods mainly include flotation, gravity separation, cyanidation and so on. More than 85% of the gold in the world is extracted by cyanidation, which is a relatively mature process for extracting gold. The cyanidation method has the advantages of high recovery rate of gold extraction, strong adaptability to ore, simple method, on-site gold production, and low cost. However, the cyanidation method has the following disadvantages: cyanide is highly toxic, causing serious harm to the e...
