Impurities in Semiconductor Materials
Most materials show some level of differences when compared to the pure materials they were derived from. Such differences are known as impurities, which are defined as foreign substances in a material that are not part of the ideal composition. In semiconduc......

Steel Slag and Slag Cement
Steel slag is a by-product of the steel manufacturing process. It is a non-metallic material consisting of mineral oxides and silicates, combined with carbonates and sulfates. Manufacturers of steel products use the slag for a variety of purposes, including road constru......
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 Gallium by Sodium Aluminate Solution Extraction
Abstract
This work studied the effects of sodium aluminum sulfate on the extraction of germanium from an industrial mineral containing high concentrations of aluminum and germanium. The extractants were studied with respect to their ability to dissolve germanium, as well as their solubility and a......
Comprehensive Utilization of Wolframite Alkali Decomposition Slag
Recycling of Molybdenum Slags by Comprehensive Utilization
Abstract
Molybdenum slag is a by-product of the chemical leaching process of molybdenum ore. In order to recycle the molybdenum slag, comprehensive utilization method can be employed. Firstly, the chemical composition of molybdenum slag ......
gold ore extraction
Gold ore is a metallic, heavy and very dense metal ore with a bright yellow color, and it is formed in a variety of shapes and sizes. Gold ore can be found in alluvial deposits, or underground in quartz veins and seams. It is commonly found in hydrated iron, magnesium and aluminum silicates, which......
Copper Concentrate Roasting
Smelting and Roasting of Copper Concentrates
Throughout the world, copper ore is mined, processed and smelted to produce copper and copper products. Copper concentrates are copper ore that have been processed and then concentrated to remove unwanted materials such as silicates and sulfur. To prod......
Water bile alum
Introduction
Bothalusite and Pyroxene are two different minerals that have similar properties, but they are both very different in terms of their chemical composition and practical applications. Biotite is one of a group of iron-bearing silicate minerals that have a common site of origin and, bec......
