Problems solved by technology

Further, there is a need for a rapid method to avoid grain-by-grain analysis which would slow down the process of separating impurities from the mineral and make said traditional techniques less viable for any commercial application

Abstract

A device for sorting contaminants from minerals includes a mineral feeding arrangement configured to feed minerals to an elongated chute member configured thereto in an inclined position for enabling free falling of the minerals in a detection zone. The device further includes an X-ray generating member to generate at least two collimated X-rays, low and high collimated x-rays, such that the collimated X- rays passes from the free falling minerals in the detection zone for being partially absorbed thereby.; The device further includes a multi-energy X-rays sensors array to sense residual low and high energy X-rays and send a signal data to an electronic module to generate a comparative valve for determining the contaminants from the free falling minerals to be sorted based on a stored threshold valve, and send a process signal to a manifold arrangement having a plurality of ejectors to generate pneumatic-pressure for sorting contaminants from minerals.

Description

technical field [0001] The invention relates to a device and method for sorting minerals, in particular to a device and method for detecting and sorting impurities from minerals (eg, coarse coal), so as to improve the quality of the minerals. Background technique [0002] The quality of a mineral (eg, coal) determines its efficiency and economics wherever it is used. In nature, minerals exist in various forms, chemistries and compositions, which are usually interwoven with some impurities that often affect the quality of minerals. In order to remove impurities from minerals and improve their quality, various conventional techniques such as wet beneficiation and dry beneficiation are widely used. [0003] In wet beneficiation techniques, minerals are crushed to the appropriate size and subjected to separation in a liquid medium based on the difference in specific gravity between mineral and impurity particles. However, since said wet beneficiation technology uses a large am...
