percolation leaching
Introduction
Leaching is the process of extracting substances from a solid material by dissolving them in a liquid. In the process, a solvent corresponds to the material to be leached, and reacts with the solid material to extract soluble substances. Leaching is typically applied in the producti......
Tantalum and niobium processing
Introduction
Tantalum is a rare, hard and highly corrosion-resistant transition metal element. It has a melting point of over 3000°C and an atomic weight of 181.0. Tantalum is silvery-gray in color and is used in the production of a number of products, including electronics, surgical implants, a......
Lithium metal refining
The Refinement of Lithium Metal
Lithium is the lightest metal ever discovered, with a low density that makes it highly malleable. Sometimes referred to as “white gold,” lithium has a wide range of uses in the automotive, aerospace, and medical industries. Although lithium is found in a variety ......
Separation of zirconium and hafnium by recrystallization
Separation of Zirconium and Hafnium by Ion Exchange Chromatography Using the Cation Exchange Resin
Abstract
Zirconium and hafnium are a pair of chemically similar elements that are difficult to separate in the environment. In this research, preparative isolation of zirconium and hafnium was achi......
Enrichment of platinum group metals by sulfuric acid method
Extraction of Platinoid Metals by Sulfuric Acid
Introduction
Platinoid metals are a group of metals including platinum, palladium, rhodium, ruthenium, and iridium. These metals are amongst the most common elements on Earth yet are also some of the rarest and most valuable. It is for these reason......
main uses of copper
Copper has been used for thousands of years for both decorative and practical applications. Throughout human history, the use of copper has become increasingly important for everyday life, and its uses are so broad and varied that it is now one of the most important industrial metals in the world.......
copper solvent extraction
Copper extraction by solvent extraction has been practiced for many decades using NTA and LIX reagents. Although other processes, such as electrorefining, have been developed to extract copper from ore, solvent extraction is more economical and efficient. The process consists of extracting copper ......
copper substitution precipitation
Introduction
Copper replacement precipitation is an essential process that is used as a coating technique. It is also known as metal plating or electroplating. It is a process of bonding metal ions to an object by passing an electric current through a solution containing a base metal. This techni......
Tin refining slag treatment
Processing of Tin Refining Slag
In the process of smelting tin from ore or refining tin, a certain amount of refining slag will be generated, which contains Sn, Fe, Cu, Si, Pb, Sb and other impurities. Tin refining slag is a kind of slag produced in the smelting and refining process of tin. This ......
