Use of rheology modifiers to adapt storage of tailings of enrichment
[摘要] Topical issues of tailing dumps operation of concentrating factories are to ensure their safety, as complex hydraulic structures, the need to extend the life of existing facilities without allocating land for construction of new ones, obtaining the necessary volumes of clarified circulating water, compliance with increasingly stringent environmental standards, reducing costs and costs. For a more compact storage in tailings dumps of enrichment wastes and large amounts of clarified water, specially developed rheology modifiers Rheomax ETD from BASF tested the technology of polymer flocculation of tail pulp of several flotation and gold recovery factories in the Chelyabinsk region. The polymers of the Rheomax ETD series of various modifications have been tested, with an increase in the consumption of which, in all cases, the angle of the natural slope of the condensed precipitate produced increased and the water loss increased. The results of laboratory studies and some data from the practice of operating the Rheomax ETD technology show that it adapts well to the conditions of existing tailing dumps of concentrating mills, where in a short time, the following tasks should be resolved: washing the beach of the tailing dump, obtaining more volumes of circulating water and improving its clarity, increasing the capacity of tailing dumps by enlarging the amount of the material laid in a cubic meter.
