The invention discloses a separation system and a separation technology of fluorite.barite type minerals. The separation technology comprises the following steps that a high-density three-product dense medium cyclone is adopted, and an automatic control system is applied to enable ore, a suspension liquid and water to reasonably flow in the technological process by means of auxiliary facility equipment such as a belt conveyor and a pump, and finally, fluorite is separated from barite to obtain a fluorite flotation process raw material and a barite flotation process raw material. According to the separation technology, separation is carried out on the minerals strictly according to the specific gravity, the selected particle size range is increased, and the separation precision, the separation stability and the separation efficiency are all improved. According to the separation technology, the fluorite and the barite are separated in advance, so that the quality and the recovery rate offinal products of the fluorite and the barite are guaranteed, the resources are effectively utilized, and the economic efficiency is improved. According to the separation technology, the problems that the quality of a fluorite.barite mineral mixed flotation product is low and the recovery rate is low are solved, the separation problem of fluorite.barite minerals is solved, and the development andutilization of the fluorite.barite minerals can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of fluorite ore beneficiation treatment technology, in particular to a gravity separation process of fluorite-barite ore. Background technique [0002] At present, the separation and purification of fluorite and barite associated ores are mostly carried out by flotation technology, and fluorite and barite have many similarities in flotation properties. , It has a great impact on the final quality and recovery rate of its products, which makes flotation separation and purification more difficult. Although some mining enterprises use gravity separation to pre-separate raw ore before flotation operations, due to the limitations of the gravity separation process (such as jigging separation), the production efficiency is low, the recovery rate is low, and the separation range is limited. Accuracy is low. Contents of the invention [0003] The purpose of the present invention is to overcome the low production ...
