trade. noun. buying, selling, or exchanging of goods and services. User Permissions. Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.The most basic of these is building stone. Limestone, travertine, granite, slate, and marble are common building stones and have been quarried for centuries (Figure [Math Processing Error] 6.5.1. 2 ). Some industrial minerals are also used for building materials (e.g. gypsum for plaster and kaolin for bricks).6.5.1: Mineral Resources Biology LibreTexts

Manganese ores used in the making of dry cells should contain 80-85 per cent of MnO2, less than 1 per cent iron and be free of such electro-negative metals such as Cu, Ni, Co and As. The functions of manganeseThey are used as raw materials in different applications. Except for fuels, metals, ores, water, and gemstones, industrial minerals are all materials extracted from the Earth’s crust by man. Non-metallics is a common synonym for industrial minerals.

Why Is Iron Ore Valuable? Behind the Scenes of Production
Iron ore is a rock from which the metal iron is extracted. About 98% of the world’s iron is used to produce steel. Pure iron is an element and a soft grayish-white metal. Other than meteorites that fall from the sky, iron is never found by itself in nature. Most iron is part of minerals that contain other elements.this process in industrial field is the flotation of iron ores which is of two types: direct and reverse flotation. The later one is again based on two different types as cationic and anionic reverse flotation. In all these processes different types of flotation reagents are used.Froth flotation process and its application Wiley Online

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine Many beneficiation techniques can be employed to upgrade the P2O5 grade of phosphate ores based on their characteristics in chemical composition and texture.

The volume of wastes generated by the mining, mineral processing and metallurgical industries now exceeds 1.8 billion mg annually. These wastes include gases, dusts solutions, sludges, and mineral materials such as mine waste, ore processing tailings and leach residues, fly ash and slags. Some of the wastes are being processed to Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times.

Ilmenite often contains intra-grain chromium (III) oxide known as chromia (Fisher-White et al. 2007), and so untreated low-grade ilmenite ores cannot be used in the sulphate route feedstock. However, either primary ilmenite concentrates (45–55 wt.% TiO 2 ) or granulated slag fines (70–80 wt.% TiO 2 ) are dissolved in 85–92% sulphuric acid
