Disproportionation metallurgy
What Is Metallurgy?
Metallurgy is a form of engineering and science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are known as alloys. Traditionally, metallurgy is divided into two categories: extractive metallurgy a......
Mine Environmental Protection
Mining and Environmental Protection
Mining is an essential activity for building and sustaining a modern society. Mining activity involves the extraction of resources, such as metals, coal, oil, and natural gas, from beneath the earth’s surface. This extraction process can have a significant imp......
smelting reduction ironmaking
Reduction of Iron
Iron ore is a mineral composed of several distinct iron-containing materials, each of which must be reduced to the elemental metal form in order to be used in industry. The process of reducing iron ore to iron is known as reduction, and it is a process that has been used in vari......

Mineral Processing and extractive Metallurgy
Mineral processing and extractive metallurgy are at the heart of many industrial processes, from the extraction of ore to the production of the final product. This means the engineering that is involved in processing ores, concentrates, and finished pr......
Extraction of Germanium by Sulfation Carrier Precipitation
内容
Abstract
In this paper, the sulfidation precipitation method for the extraction of germanium from its raw ore was described. A germanium-bearing ore sample was pulverized and mixed with sulfur dioxide gas to form sulfuric acid. The acidified sample was filtered, and the precipitate that remai......
Nickel oxide ore treatment
Nickel Ore Processing
Nickel ore is a natural resource with a wide range of uses. It is a metal that is strong, durable and rust-resistant, making it an ideal choice for a variety of industrial and household applications. As a result, the demand for nickel ore has been steadily increasing in rece......
High nickel matte selective leaching method
High Nickel-Molybdenum Selective Leaching
High Nickel-Molybdenum Selective Leaching is a process used to recover valuable metals from mineral ores. In this process, a solution containing the metal-bearing mineral is treated with an oxidizing agent, such as sodium chloride or potassium chloride, t......
Oxygen Pressure Leaching of Zinc Sulfide Concentrate
Zinc sulfide is an industrial mineral resource that is widely used in chemical, pharmaceutical and manufacturing industries. To access the zinc sulfide, an effective and efficient extraction process is needed. Hydrometallurgical processes are known to be potentially environmentally friendly, econo......
