Low Alloy Steel: Low alloy steel is a type of alloy steel that has small amounts of one or more alloying elements (such as manganese, silicon, nickel, titanium, copper, chromium and aluminium) added to it. This provides improved mechanical properties and/or greater resistance to corrosion than carbon steel. Low alloy steels are used in a …

Industrial production of iron involves several processes. These processes include extracting iron ore, crushing and grinding the ore to a fine powder, concentrating the ore, pelletizing the ore, and sintering or melting the ore. The steps may also involve using a blast furnace to reduce the ore to pig iron, and then transforming it into …

Electrolytic refining is a process that is used to purify the metal and remove any impurities that may be present. The electrolytic refining process is a technique that is used to refine various kinds of metals such as copper, gold, silver, nickel, and lead. The process starts with the metal being cast into an anode, …

Distillation refining is a process used to purify metals by separating them into their individual components. It involves heating the metal to a high temperature and then cooling it rapidly to cause the different compounds to separate. This process is used to remove impurities from the metal and create a more pure product.
Liquation is a refining process used for separating impure metals. It is most commonly used for the refining of lead and its alloys. In this process, a metal is heated in a crucible until its liquid state is attained. Impurities contained in the metal will be more soluble in the liquid state and will thus …
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 …
