Xinhai solutions: Xinhai decided to adopted heavy medium primary, gravity separation-flotation-gravity separation process .Based on the fine grain of tin ore pulp and slow fall velocity, Xinhai adopted centrifugal concentrator for roughing and discarded a large number of tailings. In addition, Xinhai used 6s shaking table to process centrifugal concentrator coarse ore and Xinhai spiral chute

J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Density gauge applications. Accurate control of density and flow rate is important in almost every form of milling, whether it be gravity concentration, flotation or leaching.In concentration methods using gravity, a steady uniform rate of feed is essential for efficient operation of all types of tables, jigs, and spirals.

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.
