Abstract

The invention provides a combined collecting agent for flotation of scheelite and gangue minerals and a flotation method thereof. The combined collecting agent for flotation of the scheelite and the gangue minerals is a mixture formed by combining caprylhydroxamic acid and sodium oleate with the mass ratio of 1:1-1:6. The flotation method comprises the steps that S1, the scheelite is ground until the 0.074 mm fineness accounts for 90% of the total; S2, sodium silicate is added into the ground scheelite, and size mixing is conducted for about 25-30 minutes; and S3, the caprylhydroxamic acid and the sodium oleate with the mass ratio of 1:1-1:6 are added for flotation collecting, and flotation is conducted for 6-8 minutes. The combined collecting agent for flotation of the scheelite and the gangue minerals is simple in ingredient, high in selectivity and good in flotation separating effect.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a combined collector for flotation of scheelite and gangue minerals and a flotation method thereof. Background technique [0002] Tungsten is an important resource, which is widely used in materials, metallurgy, chemical industry and other industrial fields. The national industrial development has a great demand for tungsten every year. Tungsten ore resources mainly include wolframite and scheelite. my country's tungsten ore resources are very rich, and wolframite is gradually being exhausted as it is continuously mined and utilized. The utilization of refractory scheelite is becoming increasingly important. [0003] Scheelite is difficult to separate mainly because it is often associated with calcium salt gangue minerals and quartz gangue minerals. The separation between calcium-containing salt-type gangue minerals and the separation from quartz gangue minerals is the flotatio...
