Iron Refining
The process of refining iron has been around since ancient times. Historically, iron ore was smelted or heated to separate the impurities from the metal, resulting in wrought iron and then the more useable steel. Wrought iron is a much softer metal than steel and can be made into a ......

Separation of Platinum Group Metals by Traditional Methods
Separation of Platinum Group Metals
The platinum-group metals (PGMs), also known as the Platinum Group, are a set of six chemical elements possessing similar properties. PGMs include platinum, palladium, rhodium, ruthenium, iridium, and osmium – all of which are precious metals and highly valued......
Silver extraction from anode slime
Electroplating is a process of electrolytic deposition in which a thin layer of relatively pure metallic deposits is formed on the surface of an electrically conductive base material. A fundamental requirement in electro-deposition is the use of a positively charged material (the cathode), an elec......
Recovery of Platinum Group Metals from Spent Supported Catalysts
Recovery of Platinum Group Metals from Spent Catalyst
catalysts are commonly used in the chemical industry for a variety of purposes. Spent catalysts contain a variety of metals including the platinum group metals (PGMs) which are valuable and could be recovered for reuse. Catalysts are used in t......
Gold Extraction from Pyrite Cinder
Introduction
pyrometallurgical processes such as smelting, roasting and calcining are used to extract valuable metals from ores and other sources. The process of pyrometallurgy is widely known for extracting gold from its ore and is typically done in two stages. Initially, the ore is roasted or h......
Platinum Group Metals Recovery from Alloy Scrap
Recovery of Platinum Group Metals from Scrap Alloy
The recovery of platinum group metals (PGMs) from scrap metals has become an increasingly valuable enterprise in recent years, as the value of the PGMs has risen dramatically. Platinum itself is the most sought-after PGM, but other metals in the ......
natural nickel
Nickel
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. It is commonly used in alloys such as stainless steel.
Nickel is one of the most importan......
Production of ferronickel from nickel oxide ore
Nickel Iron Production Using Nickel Ore
Nickel ore is a common mineral found in many parts of the world, from which nickel and iron are extracted and processed. The nickel ore is ground into small particles, which are then added to nickel-based production processes. The resulting product is known......
Crude nickel electrolytic refining
1. Introduction
Nickel electrolytic refining is the process of removing impurities from nickel by means of electrolysis. The nickel electrolytic refiner works by using a strong electrical current to force the nickel through a series of membrane cells, separating out various impurity materials in ......
Zinc smelting
Galvanizing
Galvanizing is a process that involves coating a layer of zinc on an object to protect it from corrosion and rust. This process has been used for centuries and is one of the best ways to ensure that objects remain durable for a long period of time. Although galvanizing is often used f......
