Types of metal ores

Types of metal ores Metal ores refer to ores that contain metal components. According to the different metal types, grades, and chemical composition, the metal ore can be classified as follows:

First, according to the type of metal contained can be divided into: ferrous metal ore, such as iron, manganese, chromium, etc.; non-ferrous metal ore, such as copper, lead, zinc, aluminum, tin, molybdenum, nickel, tantalum, tungsten, etc.; precious metal Ore, such as gold, silver, platinum, etc.; rare metal ore, such as oysters, oysters, oysters, etc. A single metal ore containing only one metal component and a polymetallic ore containing two or more metal components.

Second, according to the level of metal contained can be divided into: poor ore and rich ore. Take magnetite ore as an example: The grade with iron content >55% is flat furnace rich ore; the grade with iron content >50% is high grade for the blast furnace; the grade with 30% to 50% iron content is poor ore. Poor ore must be processed for smelting.

Third, according to the composition of the chemical composition can be divided into: natural metal ore, the type of ore in the form of a single element in the form of a single element, such as gold, silver, platinum, copper, etc.; oxidized ore, refers to the chemical contained in the mineral A class of ores with oxides, carbonates, and sulphates, such as magnetite (Fe2O4), iron ore (Fe2O3), white lead (PbCO3), pyrolusite (MnO2), etc.; sulphide ore, ore The chemical components contained in the minerals are sulphides such as chalcopyrite (CuFeS2), galena (PbS), sphalerite (ZnS), molybdenite (MoS2), etc.; mixed ore refers to the ore containing the top three A mixture of two or more kinds of minerals.
