What are metallic ores? Metal ores are mineral aggregates that contain metals. Most metal ores are polymetallic, i.e. the metal ore contains more than one metal. The different metals are separated during the production process. On a first level metal ores are divided into ferrous (containing Iron) and non-ferrous metal ores.

Metallic ore minerals of iron, copper, lead, zinc, cobalt, nickel, tin, tungsten, molybdenum, and plac er/ primary gold are also known from different parts of Nepal but they are not yet mined systematically. Previously two placer gold mining license were issued to private sector but they did not show any production for long time and closed.

Dark-brown to Black: color black in ferberite brown in hübnerite. Dark-brown to Black: streak darkens with increasing Fe content.

ore, metal-bearing mineral mass that can be profitably mined. Nearly all rock deposits contain some metallic minerals, but in many cases the concentration of metal is too low to justify mining mining, extraction of solid mineral resources from the earth. These resources include ores, which contain commercially valuable amounts of metals, such ...

The metallic minerals are those which contain in their composition one or more metallic elements. They are chemicals of inorganic origin, found naturally as mineral deposits. These minerals are of great importance, since they constitute the ores of most of the metals that are used in all kinds of applications.

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.
