Laterite and its special processing equipment
There are many different types of laterite. Though this article discussed iron, there are also nickel, aluminum, and other metallic components that can be infused in the clay or soil to be labeled as a laterite in geophysical terms. As the disciplines converge on this one term that means a different thing to each discipline, an understanding of the true meaning of laterite will arise and sub-categories of laterite may be used to explain the majority of the substance that makes the compound.
Laterite soil is rich in alumnium and iron, formed in wet and hot tropical areas. Almost all laterite soils are red due to the presence of iron oxides. It is prepared by the prolonged and rigorous weathering of the parent rock. Laterisation or tropical weathering is a long-drawn-out process of chemical and mechanical weathering which results in a large variety in the chemistry, grade, thickness and ore mineralogy of the ensuing soils. Laterite soils are pregnant with aluminium and iron oxides, but are deficient in potash, phosphoric acid, lime and nitrogen.
Laterite can be considered as polymetallic ore as it is not only the essential repository for aluminium but also a source of iron, manganese,nickel and chromium.
Mining machinery manufacturing industry is the basis of national independent industrial system and also an important symbol to measure the national industrial strength. Accordance with national priorities to support the development of energy, transportation and raw materials and other basic industry, the cement production line as the pillar of these industries, has been the focus of the state support. The further develop and improve of this industry will offer more international advanced level and high-quality equipments for the coal, metal and nonmetal industry, and also provide the raw materials and energy for the national economic development.
