Description
Technical field
The invention belongs to mineral operation resource field of comprehensive utilization, and in particular to a kind of pyrolusite high pressure-non cyanide process
The method of the carbonaceous gold ore containing arsenic.
Background technology
With technological progress and economic development, market is increasing to gold demand, disposable gold ore resource increasingly depleted,
Difficult-treating gold mine has become the valuable source of gold.Gold is in particulate or secondary micro- granular wrapped or dip dyeing in refractory gold ore
In sulfide mineral, it is difficult to be leached；Normal preservation carbonaceous object, humus etc. rob golden substance in ore, ADSORPTION OF GOLD of trying to be the first in leaching gold
Complex compound enters slag phase, causes the loss of gold.In the explored gold reserve in China 30% be difficult-treating gold mine, partly for containing
Arsenic Carbonaceous gold ore, the mine are China's valuable source that gold develops and utilizes from now on, therefore to the dual difficult-treating gold mine of arsenic bearing-carbon bearing
The research of stone has extremely important meaning.
Cyaniding and leaching process after being pre-oxidized at present for the processing method generally use of the carbonaceous gold ore containing arsenic, generally use roasting
Burn pre-oxidation, chlorination pre-oxidation, biological pre-oxidation method.Wherein roasting pre-oxidation is most popular method, and the method is to ores
There is a wide applicability, simple, technically reliable is safeguarded in operation, but sulphur in roasting process Minerals, arsenic are with SO2、As2O3Deng
The form of pernicious gas is discharged, arsenic, sulphur can not recycling, and cause Heavy environmental pollution.Chlorination pre-oxidation is also easy to produce chlorine
The pernicious gases such as gas, hydrogen chloride, environmental pollution are serious；Biological pre-oxidation is also known as bacterial oxidation, can be located using bacterial oxidation method
Arsenic-containing sulphur-containing mineral are managed, there is technical maturity, the less process characteristic of the Toxic of generation, but it is dense using ore pulp when bacterial oxidation
Spend it is relatively low, pretreatment time is longer, is not suitable for aerator of the processing containing the high ore of arsenic, for bioreactor require it is relatively tight,
The strain for being suitble to ore is needed, is not suitable for containing the ore for robbing golden charcoal.Using Cyanide Leaching, that there are environmental pollutions is tight after pre-oxidation
The problems such as weight.
Chinese patent CN104593583 discloses a kind of Wet-method preprocessing method of Carlin Trend refractory gold ore.This method will
Difficult-treating gold mine is mixed with sodium hydroxide, Cyanide Leaching after being pre-oxidized using hydrogen peroxide high pressure.This method can be realized to sulphur, arsenic
Pre-oxidation, but change that method preoxidation time is long, golden cyanide leaching only has 76%, and production efficiency is relatively low.
Chinese patent CN1932052 discloses a kind of integral gold refining kiln oxidizing roasting process for refractory gold ore.This method
Difficult-treating gold mine is put into tunnel oven the oxidizing roasting at 550~700 DEG C, deviates from cyaniding leaching after the harmful substances such as arsenic, sulphur, carbon
Go out.This method collects the pernicious gas of generation while the effectively harmful substances such as abjection arsenic, sulphur, carbon, but the method energy
Consumption is high, and technological process is complicated, and golden cyanide leaching only has 80%, and the golden rate of recovery is relatively low.
Chinese patent CN10301434A discloses a kind of desulfurization arsenic removing method of difficult-treating gold mine.This method utilizes microorganism
Preparation pre-oxidizes high-As and high-S gold mine, and the arsenic of package gold, sulfur mineral can be decomposed effectively, make particle by microbe-preoxidation gold 6 days
Gold is exposed, and then cyaniding is extracted.But the method production cycle is long, and strain is not easy to obtain, and can not handle carbon containing high gold mine.
In conclusion for the preprocess method of the carbonaceous gold ore containing arsenic at present, that there are technical difficulty is big, and environmental pollution is serious,
It is of high cost, the problems such as high energy consumption, resource utilization is low.Seek it is a kind of it is energy saving, efficient, environmental pollution is small, resource utilization rate is high
Method be of great significance.
