Abstract
Mentioning golden agent raw material the invention discloses a kind of improved environment protection includes potassium ferrocyanide, urea element, vulcanized sodium, sodium hydroxide, calgon, sodium carbonate.The present invention can improve the leaching rate of gold, reduce reagent consumption, it is good leach stability, while can preferably handle containing arsenic, containing the gold ore of charcoal.
Description
Technical field
The present invention relates to golden production technical fields, are a kind of purification of leaching liquor technologies, and in particular to a kind of improvement type ring
Guarantor proposes golden agent.
Background technique
85% or more gold is extracted with cyaniding in the world at present, produces gold with cyaniding, be it is a kind of more at
Ripe technique.Its advantage is that simple process, production cost is low, adaptable to ore, leaching rate height etc.；The disadvantage is that extraction time
It is long, to personal safety and and environmental pollution it is all very serious.With the exploitation of current world's gold mine, easy to handle mine is increasingly reduced or withered
It exhausts, the main resource of complicated difficult mining seam and lean ore as golden production.Research to the Comprehensive Recovery Technology of complex ore,
Have become the important topic in golden production field.In terms of extraction process, oxide ore is sorted mainly using cyaniding, with environmental protection
Requirement it is increasingly stringent, especially implementation " Environment Protect in China method " later, force enterprise administer gold and silver production to environment dirt
While dye, accelerate the research of process for cleanly preparing, to promote golden production technology to send out towards pollution-free or of low pollution direction
Exhibition.
In order to solve the hypertoxic pollution problem of cyanide, in decades, related scholar expands largely in succession both at home and abroad
Test And Research Work strives to find the nontoxic environment-friendly type of low toxicity and proposes golden agent, and the leaching gold agent studied has tens kinds, such as: sulphur
Urea method, water-chlorine process coal gold agglomeration method, thiosulfate technique, lime sulfur method, hypochlorite method etc., but by cost, stability, leaching
Extracting rate etc. influences, and industrial applications process is slow.So people also explore always some at low cost, environmental pollutions in recent years
Few environment-friendly type proposes golden agent.
It is current cyanidation gold-extracted to have the disadvantage in that reagent toxicity is big, pollution environment.2, to containing arsenic, high-sulfur Gold ore leaching
Rate is low.
