Fluorite processing production line and processing technology thereof

Abstract

The invention relates to a fluorite processing production line and a processing technology thereof. The fluorite processing production line comprises the steps of roughing, scavenging, grinding, screening, regrinding, concentrating and the like; and the current selected raw ore regrinding process is changed into the process that fine powder roughing is conducted firstly, then regrinding, screeningand concentrating are conducted on foam obtained through roughing, the load of a grinding machine in the processing process is reduced, the recovery rate of a separation plant is further improved, the selection fineness is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to a fluorite processing production line and a processing technology thereof. Background technique [0002] Fluorite is a strategic mineral, which plays an important role in the economic development of a country, and is widely distributed all over the world. It has been used as one of the advantageous mineral products for foreign exchange earning in my country for a long time. It has a wide range of uses and can be used In metallurgy, chemical industry, ceramics, cement, glass and other industries. The general characteristics of my country's fluorite mineral resources are more lean ore, less rich ore, more difficult ore, less easy ore, more symbiotic ore, and less single ore. Over the years, my country's mineral processing technology and equipment have been backward, and the technical level is low. The extraction rate of non-metallic minerals is only 20-40%, which is 10-20% lower than that of the same industry in the world. At pr...

Problems solved by technology

At present, the flotation tailings of the fluorite concentrator are between 4% and 5%, and the silica content of the fine and fine powder is between 1.8% and 2.0%. , Coarse and fine powder of a medium ore enters the ball mill and then grinds for fine powder flotation. With the gradual increase of market demand, it is imperative to control the quality of fine powder below 4%, and the fine powder and silicon dioxide below 1.5%. Yes, according to the current production process, the content of the fine fine powder into the selected raw ore-325 mesh (the minus sign before the mesh indicates that it can pass through the mesh of this mesh) is about 96%, but when observed through a microscope, the fine fine powder There are still some poor associated organisms that affect the quality of fine fine powder, and the grinder in the flotation process of the existing concentrator has basically reached a saturated state, so it is necessary to continue to study and deepen the flotation process of the concentrator to further improve the quality of fine fine powder. The fineness of selection
