Description
Technical field
The present invention relates to a kind of ore dressing additive, particularly have low toxicity, environmental protection, at ore dressing additive of precious metals such as gold trioxide, cerargyrite, copper oxide ore and its production and application.
Background technology
Precious metals such as gold, silver and bronze are precious resources.The trend of world gold and silver copper mine exploitation is rich ore, easily handles that the ore deposit is reduced day by day or exhausted, and complex ore, difficult ore and lean ore become the main resource that kustelite is produced.It is reported that rich ore seldom carries over more than 2/3 and to be refractory ore in the world at present.Therefore, in nearly twoth century,, and, become the important topic of gold and silver production field to the research of the comprehensive recovery technology of complex ore to the pretreatment process of the research of refractory ore, particularly difficult ore and the research of technology.Aspect extraction process, the main cyanide process that directly adopts of oxidized ore gold and silver ore dressing, the gold more than 85% all extracts with cyanide process in the world at present.Producing gold with cyanide process, is a kind of comparatively sophisticated technology.Its advantage is that technology is simple, and production cost is low, and strong to ore adaptability, leaching yield is high; Shortcoming be extraction time long, to personnel safety and farming, herd, the harm and the environment of fishery thanks to dye all very serious.Along with environmental protection requirement is strict day by day; particularly issued " Environment Protect in China method " afterwards in 1989; force enterprise when administering gold and silver production environmental pollution, the expedite clean-up Research on Process develops towards the direction of pollution-free or less contamination to impel the gold and silver production technology.
In order to solve the hypertoxic pollution problem of prussiate, in decades, relevant scholar has launched great deal of experimental work in succession both at home and abroad, strive to find no cyanogen, nontoxic dressing agent, the golden agent of having studied of soaking has tens kinds, for example: thiocarbamide method, water-chlorine process, coal gold agglomeration process, thiosulfate technique, lime sulfur mixture method, hypochlorite method etc., in these methods, restrict no cyanogen gold-leaching technology, to be applied to industrial subject matter be comparatively complexity of production cost height, technology.Thiocarbamide method for example costs an arm and a leg, production cost height, stable production process be poor, restricting its promotion and application.Other method does not make a breakthrough aspect industrial applications as yet.So in recent years people also to explore some costs low always, the no cyanogen that environmental pollution is few, nontoxic dressing agent, for example: the Chinese patent title: precious metal and nonferrous metal sulfide mineral composite chemical for floatating, application (patent) number: the CN99113384.6 applying date: 1999.10.29, open (bulletin) number: CN1294032, open (bulletin) day: 2001.05.09, application (patent right) people: Shenyang Mining and Metallurgical Industry Inst., address: No. 70 inventions in road (design) people: Han Shushan summary in the Tiexi District south nine, ShenYang, Liaoning Province city: precious metal and nonferrous metal sulfide mineral flotation reagent field, contain: dialkyl dithiophosphate 30%-60%, dialkyl thiocarbamic acid ester 8%-14%, mixed fatty alcohol 8%-24%, aromatic hydrocarbon oil 4%-8%, Xylo-Mucine 0%-30%, water 15%-36%, it is little that this invention has consumption, cost is low, medicament interpolation system is easy, to the metal recovery index good improvement can be arranged.
Summary of the invention
The purpose of this invention is to provide a kind of hypertoxic pollution problem that can replace existing prussiate, have that extraction yield height, cost are low, gold trioxide of stable production process, silver suboxide, cupric oxide ore dressing additive and its production and application.
The composition and the parts by weight of gold and silver ore dressing additive main raw material of the present invention are as follows:
8～15 parts in highly basic;
4～16 parts in carbonate;
12～30 parts in urea;
6～22 parts of yellow prussiate of potash.
Above-described highly basic comprises sodium hydroxide and potassium hydroxide.
Above-described carbonate comprises yellow soda ash, sodium bicarbonate, salt of wormwood and bicarbonate of ammonia.
Above-described yellow prussiate of potash chemical name is yellow prussiate of potash (chemical formula K
4[Fe (CN)
6] 3H
2O), yellow prussiate of soda (chemical formula Na
4[Fe (CN)
6] 3H
2O), pale yellow crystals is the coordination compound of iron and cyanogen formation.Be mainly used in and make paint, printing ink, pigment, pharmacy, metal heat treatmet, salt anti-hard caking agent, foodstuff additive and Iron And Steel Industry and rub leather etc.
The preparation method of gold trioxide of the present invention, silver suboxide, cupric oxide ore dressing additive is: after earlier highly basic, yellow prussiate of potash heating being reached molten state, again carbonate, urea comprehensively are heated to 600-1000 ℃, behind molten state, directly be cooled to normal temperature or place mould, be cooled to normal temperature, the demoulding obtains the ore dressing additive of blocky gold trioxide, silver suboxide and cupric oxide.
The using method of oxidation gold and silver of the present invention, copper ore dressing additive is: with above-mentioned additive water dissolution, dose with ore 50 grams～250 grams per ton, per kilogram gold and silver ore dressing additive adds 200 kilograms of dissolvings of water in advance, the method of heap pouring leaches gold trioxide, silver suboxide and cupric oxide routinely, and leaching the peak period time is 5～12 hours.
The using method of oxidation gold and silver of the present invention, copper ore dressing additive, can also add lime and admix use, method is ore to be pulverized the back add ore dressing additive of the present invention, ore per ton adds ore dressing additive 50 grams～250 grams, ore per ton adds lime 20-30 kilogram, and per kilogram gold, silver and bronze ore dressing additive adds 200 kilograms of dissolvings of water in advance, mixes with breeze, lime, the peak period of ore extraction time is 5～12 hours, reclaims gold, silver and bronze by ordinary method then.
The outstanding substantive distinguishing features and the obvious improvement of the ore dressing additive of gold trioxide of the present invention, silver suboxide and cupric oxide is:
1, can be widely used in the production in precious metal mine, the for example immersion of oxidation gold mine, cerargyrite, copper oxide ore, heap pouring etc., can also be used in industrial production industries such as plating, substitute the medicine of hypertoxic sodium cyanide, compare with other all nontoxic cyaniding medicines, have advantages such as the property of medicine is stable, the medicine environmental protection, and cost is lower, be the epoch-making product that current China advocates the friendly type of environmental protection society, will play revolutionary effect the precious metal production in the China and even the world.
2, medicine has low toxicity, environment protecting.We are special to feed dog with surpassing 10 gram medicines immersion food, and big build animal such as dog, ox, sheep, horse is drunk not fatal; Animalcule such as locust, frog is fallen in the lean solution pond of piling pouring also not fatal.Gold trioxide of the present invention is described, silver suboxide, it is low toxicity that the ore dressing additive of cupric oxide uses, security is higher.
