Abstract
The method for floating of sulphur oxygen mixed mineral in a kind of recovery mine tailing, pH regulators are made using sulfuric acid, calgon makees mineral dispersant, vulcanized sodium, ammonium sulfate, copper sulphate make the activator of composite ore, mercaptan makees composite ore collecting agent with butyl xanthate, and 2# oil makees foaming agent and obtains bulk concentrate to the progress flotation of sulphur oxygen composite ore.Sulphur oxygen composite ore in mine tailing can effectively be reclaimed using the present invention, it is being that 0.28%~1.07%, antimony grade is under the conditions of 0.24%~0.83% to ore deposit lead grade, it is the lead antimony compound refined mine that 20.87%~34.55%, antimony grade is 17.53%~28.40% to result in lead grade by the inventive method, and lead recovery is that 75.21%~82.77%, antimony recovery is 73.60%~80.75%.
Description
First, technical field
It is particularly a kind of to reclaim sulphur oxygen composite ore in mine tailing the present invention relates to a kind of flotation recovery method of sulphur oxygen composite ore
The method for floating of thing.
2nd, background technology
In multi-metal sulfide ore dressing, some metalliferous minerals are because disseminated grain size is thin, surface oxidation, liberation degree of minerals not
The reasons such as enough, technical merit and lose in mine tailing.These mine tailings are because useful value is low, bond agglomerating, surface oxidation, embedding cloth
Fine size and it is mixed with debris and is stored in by long-term heap in Tailings Dam；As the time stored up is longer, the valuable mineral surface in mine tailing
Aoxidize deeper, the difficulty of valuable metal recovery is bigger.As mineral resources are petered out, metal price is gone up, Tailings Dam
The metalliferous mineral of middle-low grade then turns into valuable secondary resource, how to reclaim as far as possible the secondary resource of this partial surface oxidation into
The focus studied for current ore dressing circle.
3rd, the content of the invention
It is an object of the invention to provide a kind of method for floating for reclaiming sulphur oxygen mixed mineral in mine tailing, it can reclaim tail
The metalliferous mineral of valuable sulphide ore and sulphide ore surface oxidation in ore deposit.
The present invention reaches above-mentioned purpose using following technical scheme：The flotation side of sulphur oxygen mixed mineral in a kind of recovery mine tailing
Method, specific steps and regime of agent are as follows：
(1) pH regulators are made with sulfuric acid,
(2) mineral dispersant is made with calgon,
(3) vulcanized sodium, ammonium sulfate, copper sulphate make composite ore activator,
(4) mercaptan makees composite ore collecting agent with butyl xanthate,
(5) 2# oil makees foaming agent,
(6) in floatation process, after mine tailing ore grinding to mineral monomer dissociation, add sulfuric acid and adjust pH5.5~6, by six inclined phosphorus
Sour sodium makees mineral dispersant, and vulcanized sodium, ammonium sulfate, copper sulphate make composite ore activator, and mercaptan is caught with butyl xanthate as composite ore
Agent is received, 2# oil makees foaming agent and carries out collecting to composite ore, and scanning recleaning three times by one roughing obtains bulk concentrate,
(7) the total consumption of medicament is：
The described method for floating for reclaiming sulphur oxygen mixed mineral in mine tailing, in use, the medicament is first configured to following
Concentration expressed in percentage by weight：
Unless otherwise indicated, percentage of the present invention is mass percent, and each component content percentage sum is
100%.
The present invention's has the prominent advantages that：
1st, the sulphur oxygen composite ore in mine tailing can simultaneously be reclaimed, obtains more high-grade bulk concentrate and high recovery
Rate.
2nd, can be to resource comprehensive utilization, and flow is simple.
4th, embodiment
