Metallurgy
The method of refining any metal is determined by its nature and the nature of its impurities. As a result, various methods are employed in this regard. The electrolytic method is the most important method and yields very pure metal.
MINERAL EXPLORATION AND MINE DEVELOPMENT
- Mining, in which ore and concentrate (or other form of semiprocessed material) are produced. Ore is the rock from which an element ultimately will be extracted. The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating mines—much less than 1%
How Electrolytic Refining Works
Electrowinning extracts metal from a solution of dissolved metal ions, commonly used in mining for metals like copper and gold. Basic Principle.

What is Petroleum Refining? Crude Oil Refining Process Steps
Petroleum Refining is defined as the industrial process of production of useful petroleum products from crude oil. The plant where the useful products are separated from crude oil is known as a petroleum refinery. Crude oil or petroleum consists of various hydrocarbons. The crude oil refining process breaks the crude oil down into various components to make useful new products.
Principles of Metal Refining and Recycling
This book is an attempt to fill the gap. This field, which we call metal refining and recycling, has become especially important due to the use of lower grade ores, increased recycling, and higher quality requirements. Our aim is to understand the principles that guide today's operation and to develop new solutions to tomorrow's problems.
