Abstract

Описаны способы уплотнения отходов, таких как металлические и неметаллические рудные процессы. Способы включают смешивание отходов с высокой концентрацией высокорастворимой в воде соли или ее водного раствора, чтобы дестабилизировать и объединить твердотельные вещества в отходах и отделять объединенные твердотельные вещества от производственной воды.Methods of compacting waste such as metallic and non-metallic ore processes are described. The methods involve mixing the waste with a high concentration of highly water-soluble salt or an aqueous solution thereof to destabilize and combine the solids in the waste and separate the combined solids from the process water.
