Abstract
The invention relates to a low-grade copper mine flotation agent, which is prepared with the following materials in part by weight: 25 to 30 parts of 208 dithiophosphate, 12 to 14 parts of ethyl isopropylxanthogenic formate, 9 to 12 parts of ammonium dibutyl dithiophosphate, 2 to 3 parts of dihenylethyl phenol polyoxyethylene ether, 1 to 2 parts of polyethyleneglycol monooleate, 3 to 4 parts of triethylene tetramine, 5 to 7 parts of menthol, 5 to 8 parts of phytic acid, 2 to 3 parts of calcium oxide, 2 to 4 parts of soda and 4 to 5 parts of activator. The foam of the flotation agent is stable, the flocculation effect is good, the flotation agent has good collecting capability within the pH range between 7 and 10, the capability of copper collection is high, yield is high, the selectivity of the agent is good, and the grade of copper is high; becauase the activator contains components such as fumed silica, dispersion is stable, moreover, permeability is good, activation is good, the duration of the activation effect is long, and the yield and grade of copper can be increased.
Description
Technical field
The present invention relates to mineral flotation agent field, particularly a kind of Treating Low-grade Copper Ores flotation agent and preparation method thereof.
Background technology
At present, China selects smelting copper mineral raw material mainly chalcopyrite, vitreous copper, bornite, malachite etc.By selecting and smelting technology condition, Copper Ores is marked three natural types with the ratio of cupric oxide and copper sulfide.I.e. sulfide ore, is less than 10% containing cupric oxide; Oxidized ore, is greater than 30% containing cupric oxide; Mixed ore, containing cupric oxide 10% ~ 30%.
The collecting agent occupying leading position in current copper ore floatation technique is the floating agent such as xanthates, thiophosphate and mercaptan, thiamines ester, xanthate, black powder ester, xanthate, but in the ore dressing of reality, the many requirements that can not reach design of result, often occur that copper, sulphur content are from undesirable, the phenomenon that in copper concentrate product, sulfur-bearing exceeds standard; Also have the productive rate of copper low, the copper concentrate rate of recovery is on the low side, causes the waste of mining deposits.
Summary of the invention
The object of this invention is to provide a kind of Treating Low-grade Copper Ores flotation agent and preparation method thereof, this flotation agent has pH strong adaptability, and collecting performance is good, selective good, the advantage that activation effect is good.
Technical scheme of the present invention is as follows:
A kind of Treating Low-grade Copper Ores flotation agent, is characterized in that being made up of the raw material of following weight portion: 208 black powder 25-30, isopropyl xanthogen ethyl formate 12-14, butyl ammonium aerofloat 9-12, Diphenethyl multiple phenol polyethenoxy ether 2-3, polyoxyethylene oleic acid ester 1-2, triethylene tetramine 3-4, menthol 5-7, phytic acid 5-8, calcium oxide 2-3, soda 2-4, activator 4-5;
