which is the oldest method of beneficiation

Gravity separation historically is the oldest method of beneficiation We have a long experience in gravity separation with the most popular equipment being spirals Modern spirals are designed for high individual capacities and come in a variety of versions – all of them carefully selected for optimal operation in given conditions Oct 30 2019Gravity separation is one of the oldest and most common gold extraction methods In the placer gold deposits the density of gold is generally greater than 6t/m3 which is different from the density of gangue Therefore the gravity separation method is the most important effective and economical method for gold mining

Beneficiation

In the mining industry or extractive metallurgy beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals which results in a higher grade product (concentrate) and a waste stream () Examples of beneficiation processes include froth flotation and gravity separation Other economic uses of the term are in use
