Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tailings treatment, in particular to tailings wastewater treatment equipment. Background Art
[0002] The mining and mineral processing processes generate a large amount of waste rock and tailings sand, which generally contain sulfide minerals (mainly pyrite, FeS2). Sulfide minerals oxidize when in contact with air and water to produce acid mine drainage. The pH of acid mine drainage is very low, and it contains a large amount of heavy metal ions and sulfates, which seriously pollute the ecological environment around the mining area. In order to avoid the above-mentioned water pollution problem, the tailings are generally cleaned to remove the pollutants. In this way, the pollution of the tailings to the environment will be greatly reduced after cleaning. When cleaning the tailings, it is necessary to ensure that the tailings themselves are highly dispersed and the cleaning is sufficient and thorough.
[0003] The traditional cleaning method is generally to use water washing, but water washing will only clean the tailings on the surface, and then use the adsorption resin module to adsorb the metal ions in the cleaned water, and then use lime powder to neutralize the acid in it.
[0004] In the process of tailings wastewater treatment, the recovery of precious metals such as gold, silver and platinum is an important part of resource utilization. Common filter, screening or cyclone separation methods can initially enrich precious metal particles. However, due to the complex composition of tailings wastewater, it contains a large amount of heavy metals, suspended matter such as clay, mineral fines and acid and alkali pollutants. As a result, iron oxide, silicate and organic flocculants co-precipitate or adhere to the precious metal particles during the screening process, seriously affecting the recovery rate and purity of the precious metals.
