Fluorite mine flotation collecting agent

Abstract

The invention discloses fluorite mine flotation collecting agent which is formed by mixing of the following raw materials by weight, namely 10-20 parts of oleic acid, 5-10 parts of number 2 oil, and 1-5 parts of kerosene. A preparing method of the agent comprises the steps that the oleic acid, the number 2 oil and kerosene are added into a stirring tank in sequence by the weight parts, and stirring is carried out under normal temperature and normal pressure for 0.5-1 hour until the materials are even. The collecting performance of the collecting agent is obviously better than that of existing collecting agent such as common oleic acid, temperature adaptive range is wide, lowest flotation pulp temperature can reach 5 DEG C, and the mineral dressing index is better than that of common oleic acid under the same temperature condition. The collecting agent is easy and convenient to prepare and use, safe, reliable and low in cost.

Description

technical field [0001] The invention relates to a flotation agent for fluorite ore, in particular to a flotation collector for fluorite ore. Background technique [0002] Most fluorite concentrators now generally use common oleic acid (Y-8) as collector, soda ash as regulator, and sodium silicate as inhibitor in flotation of fluorite ore, heating or normal temperature flotation. With the increasing development and utilization of mineral resources, there are more and more imaginations about the depletion of fluorite resources. Using oleic acid as a fluorite collector has poor collection performance, poor temperature resistance, and poor foaming properties. The disadvantage of high price, especially in winter, when the water temperature is lower than 15 ℃, it cannot be used normally, and the pulp needs to be heated to float, and the energy consumption of flotation is large. In order to improve the collection performance, saponified oleic acid and sulfonated oleic acid are als...

Problems solved by technology

However, saponified oleic acid is prepared from NaOH and oleic acid, which has many disadvantages: in the flotation alkaline system, there is no fundamental difference between the saponified oleic acid and oleic acid, and in the flotation acidic system, the saponified oleic acid and oleic acid H in the system ＋ A comprehensive reaction is produced to produce H 2 O, the collection performance will be greatly reduced; if the saponified oleic acid is placed for more than 2 months, the product properties will change, and sodium oleate will precipitate and cause stratification; NaOH is highly corrosive, and safety accidents are likely to occur during preparation

Sulfonated oleic acid is prepared from concentrated sulfuric acid and oleic acid, and it also has many disadvantages: in the flotation alkaline system, sulfonated oleic acid and OH in the system ＋ A comprehensive reaction is produced to produce H 2 O, the collection performance will be greatly reduced. In the flotation acidic system, there is no fundamental difference in the effects of sulfonated oleic acid and oleic acid; after sulfonated oleic acid is left for about 10 days, oleic acid and oleic acid sulfate will be seriously separated. Secondary mixing is required when using; sulfonated oleic acid has strong acidity, pH value ≤ 1, and it will cause serious corrosion to equipment during use, and the configuration is prone to safety accidents
