Vulcanization roasting
Introduction
sulfidation roasting is a chemical treatment process for producing a range of products. This process involves the partial oxidation of certain minerals, usually sulfides, to form a mixture of solid and liquid products. The sulfur present in the original mineral is oxidized to sulfur ......

Hot Corrosion
Introduction
Hot corrosion is a form of corrosion that occurs when certain conditions are present. It is an aggressive form of accelerated corrosion caused by combining high temperatures (313-843 K) and water or moisture within the atmosphere, often containing......
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......
Extraction of Selenium and Tellurium by Sulfation
Selenium recovery by sulfuric acid leaching
Selenium is a trace element that is essential for normal physiological functioning of all living organisms, but an excessive intake of Selenium can be hazardous to human health. As such, the safe recovery and management of Selenium from various sources ......

Cobalt-based superalloy
Cobalt Base High Temperature Alloy
Cobalt-base alloys, sometimes referred to as high temperature alloys, are used in a variety of critical parts for providing protection against high temperatures, corrosion, and other environmental stresses. These alloys contain a diverse selection of elements an......
Copper concentrate sulfate roasting
The roasting of copper concentrate is to convert the sulfide minerals into oxidized minerals, so as to separate the useful components from the sulfur and iron, and realize their extraction. The roasted copper concentrate is basically a process of oxidation and sulfidation roasting.
At present, th......
