IN-LINE TAILINGS TREATMENT PROCESS

摘要

The invention is directed towards methods and compositions for improving the processing of mineral tailings. The method involves diverting a side stream from the main line of a tailings process flow. Into this side stream an additive such as a neat polymer without dilution is added and mixed and is then returned into the main line. By doing this only a portion of the overall tailings flow needs to undergo mixing yet the additive effectively treats the tailings. Even better the process avoids the need to add water to first invert and dilute the polymer additive. As a result tailings can be processed without incurring unnecessary mixing costs and unnecessary water addition.

主权项

1. A method for improving inline mineral slurries treatment comprising successively: providing an in-line flow of slurries in a main line stream; diverting a portion of the flow from the main line stream into a side stream flow; introducing at least one additive into the side stream flow through at least one injection point to cause dispersion of the additive and to start consolidation of the solids within the slurries to produce treated slurries; passing the side stream flow into a mixing device; reintroducing the side stream flow into the main line; and transferring at least a portion of the main flow line into a deposit area.
