Steel slag phosphate fertilizer
Phosphate Fertilizer Derived From Steel Slag
Steel slag is an unavoidable byproduct of the steelmaking process. Steel slag has, until recently, largely been thrown away as waste. However, an innovative process has been developed to turn steel slag into an important resource – phosphate fertilize......

Cleaning of pressure vessels before and after metal welding and design of associated workshops
Cleanliness of Pressure Vessels Before and After Metal Welding and the Related Factory Design
Metal welding is a mechanical method used to join two metal workpieces, and it is necessary to maintain the cleanliness of the welded parts before and after welding. In the process of designing a factory......
solid superacid
Solid Superacid
A solid superacid is a type of acid that can reach concentrations exceeding those of traditional acids. It is a relatively new concept in chemistry that has only been widely known since the 1970s. It can be used for a range of applications, from basic research to industry.

Rust Remover
Rust Remover
Removing rust from tools and other metal items can be a daunting task, but with the right rust remover, the process can be quick and easy. Rust is caused by the reaction of oxygen in the air with the metal, which produces iron oxide. Rust removers, also known as rust converters, work......
TiO2
Titanium dioxide (TiO2), is an oxide of the metal titanium and is the most used white pigment due to its brightness and very high refractive index. It is produced by combining titanium metal with oxygen in a manufacturing process known as a chloride. In the production of titanium dioxide, the most......
Uranium extraction by wet process phosphoric acid
Wet phosphoric Acid Leaching of Uranium Ores
Introduction
Uranium extraction from ore is an important industrial and research topic due to the radioactivity and potential for nuclear proliferation of this strategic resource. Many methods have been developed over the years for extraction of urani......
Separation of zirconium and hafnium by solvent extraction
Abstract
This study investigated the use of a zirconium hafnium solution extraction method to separate zirconium and hafnium. The purpose of this study was to identify optimal operating conditions for extracting zirconium and hafnium using an ion exchange resin. The extraction system consisted of......
Nickel alloys resistant to crevice and phosphoric acid corrosion
Nickel Alloy Resistant to Crevice Corrosion and phosphoric Acid Corrosion
Introduction
Nickel alloy is a type of alloy material composed of nickel as the base element, chromium and various other alloying elements. It has excellent properties such as heat resistance, corrosion resistance and high ......
Enrichment of platinum group metals by pressure leaching
Abstract
The enrichment of platinum group metals (PGMs) from low-grade ores needs a new and efficient technique to separate PGMs from other metals. High-pressure leaching (HPL) is a potential method for PGM extraction because it uses high pressure, temperature and chemical environment to leach ou......
Extraction and separation of platinum group metals
Introduction
Platinum group metals (PGMs) are a group of six transition metals—platinum, palladium, rhodium, iridium, osmium, and ruthenium—which have similar physical and chemical characteristics. They have high melting points, neutral oxidation states, good catalytic properties and resistance......
