Mineral processing refers to the process of separating the valuable minerals from gangue veins and extract as much valuable mineral as it can. There are tens of minerals contained in the rock or vein in different forms, thus various processing technologies are applied for different processing.
Coal gangue identification flowchart. Technical features Wide processing size range It can handle 30- 600mm raw coal. The upper limit of separation is 600mm and the lower limit is 30mm. High separation accuracy The rate of gangue removing is over 95, the rate of coal in gangue is less than 2, and the separation effect is significant.
Mar 27, 2020 Coal is one of the main sources of human energy. In the process of coal mining, separating gangue from coal has great significance for environmental protection and energy conservation. The core problem in the separation of gangue is the recognition of coal and gangue. In this study, multispectral technology was used to identify gangue. First, set up a data acquisition system
A gangue in chemistry can be defined as an unwanted material or impurities in the form of sand, rock or any other material that surrounds the mineral in an ore deposit. This substance is common when it comes to the aspect of mining. Usually, gangue has to be separated from mineral and the process used is known as mineral dressing, mineral ...
