Problems solved by technology

But at present, the collectors in the flotation agents used in non-ferrous metal beneficiation production, such as kerosene, diesel oil and transformer oil, are all refined oils, which cannot be recovered after use. They are completely production consumption and consumption of petroleum resources. These collectors They all belong to petroleum resources. With the shortage of petroleum resources and the rise of oil prices in the world today, the cost of flotation of minerals is very high, which has greatly affected the economic benefits of non-ferrous metal beneficiation enterprises.

Embodiment 1

[0016] The following is an example of a flotation agent used in the rough separation of molybdenite produced by using the oily sludge of the crude oil storage tank of the oil field gathering and transportation station.

[0017] Take 100kg of oily sludge with a crude oil content (average value) of 30% to 35%, 5kg of terpineol oil, 14kg of lime, and 21kg of water glass as a flotation agent to roughly separate about 12 tons of molybdenite powder. When these oily sludges are used as collectors, the silt in them must first be pulverized, and the light product oily sludge and heavy oily sludge or crude oily sludge are separated according to the flotation operation process requirements (operating temperature, coarse selected or carefully selected) in proportion to adjust the molecular weight of the contained oil, and finally emulsify the oil, mud, and water before use. The specific steps are: before the flotation production operation, first crush the sand particles and other solids c...

Embodiment 2

[0019] The following is an example of a flotation agent used in the roughing of gold ore produced by using the oily sludge of the crude oil storage tank of the oil field gathering and transportation station, wherein the regulator only uses water glass as a medicament.

[0020] Get 6kg of oily sludge (average oil content is 20% to 30%) in the oil refinery sewage treatment recovery tank, 0.5kg of terpineol oil, and 0.5kg of water glass to form a flotation agent. In the enrichment production, Through flotation, 1 ton of high-arsenic, high-sulfur, fine-grained gold ore can be roughed. This gold ore powder contains an average of 6.68 grams of gold, 4.01% of sulfur and 5.43% of arsenic per ton, which belongs to refractory gold ore. In the flotation enrichment process, the treatment method of the collector is the same as in Example 1, the pulp concentration is 30% to 35%, the operating temperature is 30 to 40°C, and the order of dosing is water glass, oily sludge emulsion and terpine...

Abstract

The invention relates to a non-ferrous metal mineral flotation agent which comprises a collecting agent, a foaming agent and a regulating agent, wherein the collecting agent is oily sludge comprising kerosene and/or diesel oil and/or transformer oil and/or heavy oil and/or crude oil. The foaming agent is pine wine oil or hexyl alcohol or n-caprylic alcohol or octanol, and the regulating agent is lime and/or water glass. Compared with the prior art, oily sludge produced in the processes of production, transportation and storage of an oil field, an oil refinery and the like is in resource utilization as the collecting agent of the flotation agent, and an agent produced under the coordinating function of the collecting agent, the foaming agent and the regulating agent forms to be the novel flotation agent used for mineral processing production of non-ferrous metal, using amount of various product oil is greatly saved, and agent cost of the flotation agent for flotation and enrichment production of the non-ferrous metal is reduced.

Description

technical field [0001] The content of the invention belongs to the technical field of nonferrous metal mineral flotation preparations, and relates to a nonferrous metal mineral flotation agent. Background technique [0002] The grade of non-ferrous metal minerals is generally low and cannot meet the industrial production standards, so it is necessary to enrich the metals in the raw ore. There are many technical methods for metal enrichment in raw ore, but flotation is the most widely used. Mineral flotation enrichment production is carried out under the action of flotation agent. The main component of the flotation agent used is collector, which is an organic substance that can interact with the surface of the mineral and can generate hydrophobic water on the surface of the target mineral. The thin film reduces the wettability of the mineral surface and improves its buoyancy, which is conducive to the mutual attachment of mineral particles and air bubbles. The buoyancy of t...
