  In the beneficiation of quartz ore, the separation of different mineral components and quartz is an important issue, which has a great influence on the purity of quartz concentrate. Mineral components commonly found in quartz ore include mica, feldspar, iron-bearing minerals, and apatite. In this article we describe how the common mineral components of quartz are separated. 1. Separation of mica minerals from quartz In quartz ore, after grinding and dissociation, the mica composed of layered structure exposes a large number of anions on the surface, which can be collected by cationic collectors in a wide range of pH values, although mica minerals and feldspar minerals collect The collection properties are similar, but the flotation pH range of mica is wider, so mica minerals can be flotation first under strong acidic conditions. The reagent system for mica mineral flotation separation is relatively simple. Generally, the slurry concentration can be adjusted to between 30% and 35%. Di

  There are many minerals associated and associated with nickel ore. Whether mineral processing is required depends on the nickel content in the ore. Rich ore containing more than 3% nickel can be directly smelted; ore containing less than 3% nickel requires mineral processing. Nickel ore flotation method For ores with a nickel content of less than 3%, beneficiation is required. The commonly used beneficiation method is flotation. Magnetic separation and gravity separation are often used as auxiliary beneficiation methods for flotation in nickel ore beneficiation. Collectors and foaming agents for flotation of copper sulfide minerals are often used in flotation of copper-nickel sulfide ores. A basic principle of determining the flotation process is to rather make copper enter the nickel concentrate, and avoid nickel entering the copper concentrate as much as possible. Because the nickel in the copper concentrate is lost in the smelting process, and the copper in the nickel concentrate
