Novel mineral separation process for gravity separation of useful minerals such as magnetite, apatite, ilmenite and sulfide minerals and product

Abstract

The invention discloses a novel mineral separation process for gravity separation of useful minerals such as magnetite, apatite, ilmenite and sulfide minerals and a product obtained by implementing the process. The product comprises powdered iron minerals, apatite concentrate, the ilmenite, brass concentrate and sulfur concentrate. The mineral separation process is simple, easy to implement, fine in mineral separation effect and high in working efficiency, sufficiently takes the advantage that the sulfide minerals can be sorted by recovering apatite agents, and the drawback of no recovery of the sulfide minerals in a traditional process is eliminated. The comprehensive utilization rate of resources is increased, useful resources are maximally recovered, the magnet grain size of ultra-low-grade magnetite is non-uniform, qualified concentrate can be separated according to gravity and timely extracted, energy waste due to the fact that qualified concentrate is outputted only when all materials are grinded to below a certain size fraction in the past is avoided, process flow is simplified, cost is reduced, the advantages of various devices are maximally taken, the resources are sufficiently used, and wide popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the mineral processing field, and in particular relates to a novel mineral processing process for re-selecting useful minerals such as magnetite, apatite, ilmenite, sulfide ore, and a product obtained by implementing the process. Background technique [0002] In our lives, iron can be regarded as the most useful, cheapest, most abundant and most important metal. The annual output of steel represents the modernization level of a country. For the human body, iron is an indispensable trace element. Iron is also an indispensable catalyst for plants to produce chlorophyll. [0003] About two-thirds of phosphorus is used in phosphate fertilizers. Phosphorus is also used in the manufacture of phosphoric acid, fireworks, incendiary bombs, pesticides, etc. Phosphorus is widely distributed in the biosphere, and its richness in the earth's crust ranks among the top 10, and its concentration in seawater belongs to the second category. ...

AI Technical Summary

Problems solved by technology

[0007] With the development of the national economy, the demand for iron, phosphorus, titanium, copper, and sulfur is increasing day by day, and our traditional process of processing this type of ore in the past is to only recover magnetic iron. With technological progress and market demand, we start from iron selection Phosphorus and titanium are recovered from tailings, but non-ferrous metals are not recovered, and iron selection does not give full play to the technological advantages, resulting in high costs
