Abstract
Copper oxide ore floatation agent is made with, by weight, 20-25 parts of white oil, 8-10 parts of crude oil, 13-15 parts of No.2 oil, 12-15 parts of calcium lignosulphonate, 4-7 parts of sodium silicate, 4-5 parts of sodium dodecyl sulfate, 10-12 parts of ammonium dialkyl dithiophosphate, and 4-5 parts of activator. The flotation agent features good foaminess, foam stability, pH stability, good flocculation effect, and good inhibitory action against other ores; the floatation agent is capable of well collecting copper oxide, copper yield is high, the floatation agent is well selective, and copper grade is high; the activator contains the components such as jade nanopowder, has good permeability and activity, the activation effect lasts long, and the yield and grade of copper is increased; the flotation agent is easy to recover and has low environmental pollution.
Description
Technical field
The present invention relates to mineral flotation agent field, particularly a kind of Oxide Copper Ore Flotation agent and preparation method thereof.
Background technology
At present, China to select smelting copper mineral raw material be mainly chalcopyrite, vitreous copper, bornite, malachite etc.Press selecting and smelting technology condition, Copper Ores is marked to three natural types with the ratio of cupric oxide and copper sulfide.Be sulfide ore, containing cupric oxide, be less than 10%; Oxidized ore, is greater than 30% containing cupric oxide; Mixed ore, containing cupric oxide 10%～30%.
The collecting agent that occupies leading position in current copper ore floatation technique is the floating agents such as xanthates, thiophosphate and mercaptan, thiamines ester, xanthate, black powder ester, xanthate, but in actual ore dressing, 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 Oxide Copper Ore Flotation agent and preparation method thereof, this flotation agent has pH value stabilization, foam stabilization, and solidifying wadding is effective, and collecting performance is good, selectively good, the advantage that activation effect is good.
Technical scheme of the present invention is as follows:
A kind of Oxide Copper Ore Flotation agent, it is characterized in that being made by 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 by 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 that each raw material is mixed, and is heated to 60-65 ℃, under 2000-2500 rev/min, stirs 40-50 minute, obtains.
The preparation method of described Oxide Copper Ore Flotation agent, it is characterized in that: other composition except activator is mixed, at 45-50 ℃, stir 10-15 minute under 2000-3000 rev/min, add again activator, under 2000-3000 rev/min, stir 20-30 minute and get final product.
Beneficial effect of the present invention
Flotation agent of the present invention has that foaminess is good, foam stabilization, pH value stabilization, effective, good to other mineral inhibitions feature of solidifying wadding, and good to the collecting performance of cupric oxide, the productive rate of copper is high, selectively 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 recovery easily, environmental pollution is little.
The specific embodiment
A kind of Oxide Copper Ore Flotation agent, by following weight portion (kilogram) raw material make: 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 by following weight portion (kilogram) raw material make: nanometer jade powder 3, alginic acid 2.5, acrylic glycidol ether 1.5, paregal O 2.5, disecoctylmaleate sodium sulfonate 2.5, vinylacetate 2.5, hydrogen peroxide 5, sodium hydrogen phosphate 5, water 45; Its preparation method is that each raw material is mixed, and is heated to 63 ℃, stirs 45 minutes under 2300 revs/min, obtains.
The preparation method of described Oxide Copper Ore Flotation agent is: other composition except activator is mixed, at 48 ℃, stir 13 minutes under 2500 revs/min, then add activator, stir 26 minutes and get final product under 2500 revs/min.
By the flotation agent of the present embodiment, for Oxide Copper Ore Flotation, copper productive rate reaches 3.9%, and copper grade reaches 16.8%, and copper recovery reaches 93.1%.
