Abstract
An oven for removing arsenic and sulfur from auric sulfide ore is characterized by that a rotating platform and an non-oxygen circulating equipment is used inside the oven, so that dearsenic and dsulfure and high gold recovery is achieved. In addition, tail gas treatment and oven body leckage-proof equipment are installed, so that the tail gas reaches the discharge standard requirement.
Description
The present invention relates to the gold mine treatment facility, a kind of specifically about card crop type and gold trisulfide ore pre-treatment pozzuolite cooking stove, its objective is that providing a kind of to society can remove the arsenic in the ore, sulphur to meeting Gold Ore smelting production requirement with pyrogenic process, can make institute's waste discharge gas meet the novel cooking stove of environmental emission standard again.
The method of pyrogenic process arsenic removal at present,, sulphur removal is the method that ore and coal is loaded in mixture with reverberatory furnace or common kiln.These two kinds of methods all have two kinds of phenomenons to produce: the one, cause burning, and the gold in the ore deposit can be wrapped up in by anti-package because of burning, causes the rate of recovery to reduce, and the 2nd, burning is not enough, causes arsenic, sulphur can not distil and remove unclean.The above results is uneven and do not satisfy the condition that the arsenic removal need just can carry out and cause under anoxia condition owing to temperature in the body of heater, thereby the phenomenon that the rate of recovery that forms gold reduces, and these cooking stoves are not because be provided with better dust arrester installation, and exhaust gas discharged does not meet country's " three wastes " emission standard.
The purpose of this invention is to provide a kind of main furnace temperature equilibrated, can reach the required anoxia condition of arsenic removal, do not cause ore burning or not enough, novel cooking stove waste gas index qualified discharge standard, that be provided with mechanical automatic feed/discharge breeze device of burning, to reach the cooking stove of ore gold metallurgy bottom technology high-recovery.
The object of the present invention is achieved like this:
A kind of arsenious-sulfur oven for pretreatment of vulcanizing gold ore is used for pyrogenic process arsenic removal sulphur removal.One has the combustion chamber 2 of thermal source, the top of combustion chamber 2 be provided with the concentrically ringed plane of mobile rotation charging platform 4 ', inner anaerobic thermocirculator 8,10 and the settling pocket 11 that up is provided with successively, cooling pool 15, vacuum fan 14, the dust arrester installation of two groups or more that dust chamber 17 is formed, and be provided with machinery turnover breeze materials device 20 automatically.Each part mentioned above all is contained in the anti-body of heater exhaust gas leakage shell 18, and in the enclosed chamber 26, this covering closed chamber 26 is provided with fresh air Supply Structure 21 to this anti-leak shell integral installation outside.
The a kind of of described cooking stove specifically is configured to:
