Problems solved by technology

Chinese patent CN102962144A discloses a kind of oleic acid with a degree of saponification of about 50% as a collector, and a method for flotation and separation of bauxite; A method for enriching fluorite by segmental flotation with oleic acid; Chinese patent CN102600985A discloses a method for flotation of ilmenite and iron oxide ore using a collector mixed with oleic acid, oxidized paraffin soap and fatty acid; The Chinese application CN107922993A of Heinkel Company adopts alkyl sulfosuccinate of alkoxy fatty alcohol as the flotation agent in non-sulfurized ore flotation, which can improve the flotation efficiency and reduce the cost of flotation agent to a certain extent. usage, but the preparation method of this flotation agent is complicated, the production cost is high, and it is difficult for enterprises to accept it when it is used on a large scale.
As a collector, oleic acid has strong versatility, good collection capacity, and high flotation recovery rate. It is widely used in the mineral flotation industry. However, oleic acid has poor selectivity, extremely low water solubility, and poor dispersibility. Flotation During the process, it is necessary to increase the temperature of the pulp to promote the dispersion of oleic acid in the pulp, resulting in an increase in energy consumption and cost during the beneficiation process
The substitutes of oleic acid, such as oxidized paraffin soap, have certain adaptability to low-temperature pulp, but their collection performance is not as good as that of oleic acid.

Abstract

The invention provides an ore collecting agent for collecting oxidized ore such as ilmenite and a preparing method of the ore collecting agent for collecting oxidized ore such as ilmenite and belongsto the technical field of oxidized ore floatation collecting agents. The ore collecting agent for oxidized ore such as ilmenite is used after ammonium dibutoxy dithiophosphate, edentate, maleate, oxidized paraffin soap and the like are mixed, has the beneficial effects of being good in water solubility, good in dispersibility and high in preferential adsorption capability on aimed ore and is mainly used for floatation separation of valuable ore in oxidized ore such as ilmenite, scheelite and wolframite. The preparing method of the re floatation collecting agent for oxidized ore is simple in process, operation is easy to control, and the prepared collecting agent has the beneficial effects of being high in selectivity, good in dispersibility, small in agent dosage, high in beneficiation comprehensive efficiency and the like and has very important significance in promoting beneficiation of ore such as oxidized ore.

Description

technical field [0001] The invention relates to a flotation collector for oxidized minerals such as ilmenite, and belongs to the technical field of mineral flotation collectors. Background technique [0002] There are about 20 proven minerals containing tungsten on the earth, but the ones with economic development value are scheelite and wolframite. Due to the relatively high weight of tungsten ore, with a specific gravity between about 6-8, high grade and recovery can be achieved through gravity separation when only coarse particles are released. However, tungsten ores typically occur at points of contact between tungsten-bearing ores in the form of granite, in quartz ore, and in the form of carbonate sedimentary rocks. However, in actual mining, it will be found that scheelite is produced as fine particles. When gravity separation is used, many fine particles are generated due to high brittleness during crushing or grinding, so the recovery rate is greatly reduced. There...
