Ultra-fine Screening Of Dry Mineral Powders | Agg-Net
The fine and ultra-fine screening (defined as the application of cut points in the range 30µm– 200µm) of powders, even when dry, is one of the most difficult tasks in the field of minerals processing. It is essential to achieve efficient recovery, at an economic throughput rate, of required products in the form of sharply defined fractions ...
Jigging
The liquid pulsates, or "jigs" up and down, causing the heavy material to work down to the bottom of the bed and the lighter material to rise to the top. Each product is then drawn off separately. Jigging is one of the oldest processes used for concentrating heavy mineral particles from the light.

Introduction to Mineral Processing
In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

The objective of mineral processing is to liberate and separate the valuable minerals from the gangue. In order to separate the valuable minerals from the gangue, it is necessary to crush and/or grind the rocks to a size where they are partially or fully exposed, or "liberated". The process of crushing and grinding is referred to as ...

What You Need To Know About Mineral Processing
In simple terms, mineral processing is separating commercially valuable minerals or metals from other rocks. It's not often that you dig up a large gold nugget. Instead, small particles of gold can be found mixed in with other minerals, metals, and rocks, some valuable, and some not. The collection of all these materials together is called ore.
