Polymetallic deposits are metal ore deposits that contain more than one useful metallic element or metal. Polymetallic deposits are commonly associated with hydrothermal activities in magmatic arcs, sedimentary rocks, and volcanic-hosted deposits. The vast majority of polymetallic deposits discove......

Arsenite
Heavy metal pollution from mine drainage containing lead, cadmium, zinc and other pollutants has become a serious problem in modern society. Numerous studies have found that arsenic and antimony are among the most frequent heavy metal pollutants of mining.
Arsenic and antimony are widely distribu......
Nickel ore beneficiation
Nickel ore is a kind of ore that contains nickel minerals. Nickel ore is divided into sulphide ore and oxide ore. Nickel oxide ore is mostly composed of nickel oxide which is an insoluble substance and is difficult to be employed in industry directly. Therefore, a process to recover the nickel oxi......
Tungsten molybdenum bismuth polymetallic ore beneficiation
Tungsten, also known as Wolfram, is a type of metal ore whose ore occurs mainly in veins found in certain volcanogenic-type rocks. It is a hard, wear-resistant, and extremely ductile metal. Tungsten has the highest melting point of all the metals, making it useful for a range of industries.

Application of Nitrogen in Microalloyed Steel
Application of Nitrogen on Microalloyed Steels
Abstract
Nitrogen, a non-metallic element, is an important additive to steels and the inclusion of nitrogen in steels can affect the steel’s physical, chemical, and mechanical properties. Microalloyed steels, which are low alloy steels, form a sepa......
Oxidation characteristics of direct reduced iron in air
？
Iron is one of the most essential and abundant metals found in the Earths crust. Its importance to civilization is well recognized, having been used since the Bronze Age for tools and weapons, and playing a major part in the industrial revolution. Iron has also long been an important component o......
Main characteristics and uses of ferritic stainless steel S11703 00Cr17
Introduction
The 00Cr17 steel is a type of iron chromium stainless steel, belonging to the iron-chromium-nickel group. It is an austenitic corrosion-resistant stainless steel, with a high chromium content, which gives it excellent corrosion resistance - particularly in sea water. This makes it at......
Corrosion resistance of chromium-nickel-manganese-nitrogen austenitic stainless steel 00Cr22Ni13Mn5Mo2N (Nitronic50)
Corrosion Resistance of Nitronic50 (00Cr22Ni13Mn5Mo2N) Austenitic Stainless Steel
Introduction
Nitronic50 is an extremely corrosion resistant austenitic stainless steel. It is a great choice for use in highly corrosive environments due to its combination of good strength and excellent corrosion ......
Chemical composition of urea grade 00Cr17Ni14Mo2 (316L, UG) steel
Introduction
00Cr17Ni14Mo2 (316L, UG) steel, also known as marine grade stainless steel, is a low-carbon alloy containing 17% chromium, 14% nickel and 2% molybdenum. 316L UG steel is ideal for use in applications near or in seawater where maximum corrosion resistance is required. It is resistant ......
Low-magnification microstructure inspection of steel
1. Introduction
When it comes to steel, low-magnification microstructural examination plays an important role in assessing the quality and suitability of the material. This technique enables the determination of the steel type as well as the evaluation of physical properties such as strength and ......
