Refining of metals is the process of purifying a metal by removing impurities from it. This is done by either electrolytic, chemical, or thermal processes. The primary purpose of refining is to produce a metal with greater purity or to produce a more uniform alloy. Refining can also be used to separate metals from their …
Reduction of oxide ores is accomplished using a variety of methods, such as smelting, leaching, and roasting. Smelting involves the use of heat and a reducing agent, such as coke, to separate the metal component of the ore from its oxide component. Leaching uses a chemical solution, such as sulphuric acid, to dissolve the metal …

Roasting is a metallurgical method for extracting ore from an ore deposit. It is a process in which ore is heated to a high temperature in the presence of oxygen to cause the metal values to oxidize and be released from the ore. This method is used to extract metals such as copper, zinc, and …
Calcination is a thermal treatment process used to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The process involves heating a material to a temperature that is below its melting point (if applicable). This process is used in a variety of industries, such as metallurgy and ceramics, to change the …
Leaching ore is a process by which valuable metals are extracted from ore by dissolving them in a solvent such as water or acid. The process involves the use of chemical reagents that react with the valuable metal in the ore, causing it to dissolve and then be extracted from the solution. The leaching process …
Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. Magnetic separators are widely used for magnetic separation. Magnetic separators are extensively used to concentrate ores, particularly iron ores, when …
Froth floatation is a process used to separate materials based on their relative affinity for air bubbles. It is commonly used in the mining industry to separate valuable minerals from unwanted material or other valuable minerals. The process involves the introduction of air bubbles into a mixture of finely ground ore and water. The lighter …
Levigation or hydraulic washing is a process used to separate particles in a suspension or other mixtures by the process of sedimentation. It involves the use of a liquid such as water to force the particles to settle out of the suspension. The particles are then collected and separated from the liquid. This process is …

Detergent is a substance used for cleaning, usually made from synthetic or man-made sources. It is typically used to remove dirt, grease, and other contaminants from surfaces and fabrics. Detergents are available in a variety of forms, including liquids, powders, gels, and tablets. They can be used for a wide range of cleaning tasks, including …
Soap is a salt of a fatty acid that is used in conjunction with water for washing and cleaning. It is usually made from lye and vegetable or animal fat. Soap has many applications in chemistry, including as a surfactant, for its ability to reduce the surface tension of water. It is also used in …
