Introduction: Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be utilized. Can be divided into metal minerals, non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called ore grade, and precious metal ore such as gold and platinum is expressed in grams per ton, and other ores are usually expressed as a percentage. Common ore grades are used to measure the value of ore, but the composition of the same active ingredient ore, the minerals in the ore (the minerals in the ore that are of little use and the amount of useful constituents), and the amount of harmful impurities also affect the ore value. Metal ore refers to minerals from which metal elements can be extracted, such as iron ore, copper ore, lead ore, zinc ore, lead-zinc ore. product article click: company homepage:
