Non-ferrous metals generally refer to all metals except iron, manganese, chromium and iron-based alloys. Non-ferrous metals can be classified into heavy metals (such as copper, lead, zinc), light metals (such as aluminum, magnesium), precious metals (such as gold, silver, platinum) and rare metals (such as tungsten, tin, molybdenum, nickel, niobium).
Non-ferrous metal ore is often symbiotic with a variety of metals, so it is necessary to rationally extract and recover useful components for comprehensive utilization in order to make rational use of natural resources. Different metal ores and different metal ores exist in different states, and most of the mineral processing methods are different. It is our goal to select the correct beneficiation method and make comprehensive utilization of the ore.
Ferrous metals are commonly referred to as iron, chromium and manganese. The presence of ferrous ore in nature is also diverse. Iron ore has magnetite, hematite, limonite, etc.; chrome ore has chromite ore, chrome spinel ore; manganese ore has manganese oxide, manganese carbonate, etc.;
Different ores exist, different beneficiation methods are required, and sometimes joint beneficiation is required. The beneficiation of ferrous ore is mostly related to magnetic separation, but the choice of magnetic field strength is crucial.
Non-metallic minerals include a very wide range. Our common non-metallic minerals mainly include graphite, phosphorus, fluorite, potassium sodium feldspar, magnesite, and barite.
The different nature of the ore has a great influence on the beneficiation effect. The correct ore dressing method and ore dressing conditions can be used to obtain excellent concentrate products.
