Advantages and disadvantages of ion exchange resin method compared with carbon slurry method

2) The resin can be desorbed well under low temperature and normal pressure, and can be regenerated after simple desorption after desorption, and the activated carbon must be desorbed at a higher temperature, and it needs to be periodically activated at a high temperature after desorption;

3) Organic substances have little effect on the adsorption process of the resin. For example, for argillaceous oxide ore, carbonaceous ore, slurry containing flotation agent, and other ores difficult to be treated by conventional cyanidation, it has good adaptability and high recovery rate;

4) The resin can adsorb free cyanide ions, thereby achieving recycling and controlling pollution.

However, the disadvantage of the ion exchange resin method is that the selectivity is poor, the viscosity of the resin is small, and the screening operation of the finer mesh is required, which increases the difficulty of separating the tree from the slurry. Research on high performance resins should be strengthened.
