1) Ferrous minerals: The metallic minerals that contain iron are known as ferrous minerals. In the total production of metallic minerals, 75% is constituted by ferrous metallic minerals. Its common examples include iron ore, manganese, chromite and nickel. 2) Non-Ferrous minerals: The metallic minerals that don't contain iron are known as non ...
Moengo Minerals started production in 2013 of meta-kaolin, which acts as an additive or substitute for cement in building materials. The possibility of exploitation of the kaolin for filling and coating, in the paper industry, depends on whether its quality meets the rigid industry specifications of particle size (distribution), particle shape, brightness, grit content and …

Non-metallic materials are any materials, both synthetic and natural, which do not contain metal. These materials are able to retain their unique chemical properties during the machining process. There are a wide variety of non-metallic materials, including: Rubber Ceramics Fiber Plastics
Non-metallic minerals are those minerals that do not contain metals and are organic in origin like fossil fuels or non-organic in nature like sand, gravel, mica, limestone, clay, graphite. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
