Description
Technical field
The present invention relates to mineral flotation agent field, particularly a kind of Copper oxide ore floatation 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 Copper oxide ore floatation agent and preparation method thereof, this flotation agent has pH value and stablizes, foam stabilization, and solidifying wadding is effective, 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 Copper oxide ore floatation agent, it is characterized in that being made up of the raw material of following weight portion: white oil 20-25, crude oil 8-10, No. two oily 13-15, calcium lignosulfonate 12-15, waterglass 4-7, dodecyl sodium sulfate 4-5, dialkyldisulfide are for ammonium phosphate 10-12, activator 4-5;
Described activator is made up of the raw material of following weight portion: nanometer jade powder 2-4, alginic acid 2-3, acrylic glycidol ether 1-2, paregal O 2-3, disecoctylmaleate sodium sulfonate 2-3, vinylacetate 2-3, hydrogen peroxide 4-7, sodium hydrogen phosphate 4-6, water 40-50; Its preparation method is mixed by each raw material, is heated to 60-65 DEG C, stirs 40-50 minute, to obtain final product under 2000-2500 rev/min.
The preparation method of described Copper oxide ore floatation agent, it is characterized in that: by other composition mixing except activator, at 45-50 DEG C, under 2000-3000 rev/min, stir 10-15 minute, add activator again, stir under 2000-3000 rev/min 20-30 minute and get final product.
Beneficial effect of the present invention
The feature that flotation agent of the present invention has that foaminess is good, foam stabilization, pH value are stablized, solidifying wadding is effective, good to other mineral inhibitions, good to the collecting performance of cupric oxide, the productive rate of copper is high, selective good, copper of high grade; Activator of the present invention contains the compositions such as nanometer jade powder, stably dispersing, and good penetrability, and reactivity is good, and the activation effect duration is long, can improve productive rate and the grade of copper; And this flotation agent reclaims easily, environmental pollution is little.
