Water purification of sulfates by liming when adding reagents containing aluminum

Technology of the comprehensive desalination of wastewater from mines

“…Article [11] investigates the processes of water purification by sulfates when processing with lime, sodium aluminate. The disadvantage of sodium aluminate is the large values of residual water alkalinity.…”

Determining the influence of the medium reaction and the technique of magnetite modification on the effectiveness of heavy metals sorption

“…For the mining industry the method, developed in [2], provides a cost-effective treatment process for dumping in water bodies with the subsequent disposal of sediment. It was shown, that reagent purification is a very promising method of water demineralization, but the selection of reagents should be directed to making the process easier and simpler and avoiding re-contamination.…”

“…However, there are no data on the disposal of used-up sorbents. Thus, having explored papers [2][3][4][5][6][7][8][9][10][11][12][13][14], it is possible to conclude that the problem of development of highly effective economic methods of deep-water purification from ions of heavy metals in the presence of hardness ions remains unresolved. To solve these problems, it is advisable to use the modified sorbents based on magnetite, which make it possible to remove ions of heavy metals from water with a high degree of purification.…”

Devising a corrosion inhibitor for steel ST37-2 in a water-oil mixture

“…It is worth noting that most domestic oil pipelines are operated under conditions of intensive internal corrosion; the operation of wells is associated with the release of mineral particles, in particular sand, which also leads to the wear of the equipment. High corrosion activity at oil extraction is the feature of water from mines as it is characterized by high mineralization [2,3]. Crude oil causes the corrosion of steel pipelines since it is heated to a temperature of 80 °C and contains up to 30 % of water when it is pumped [4].…”
