The invention pertains to a process for separating mixtures of solids based on their densities. The present invention also relates to the use of a separating liquid (L) for separating plastic solids from metal-containing solids based on their densities, wherein the separating liquid (L) has a density d3 such that 1.5<d3<2.0; wherein the solids have a particle size ranging from 0.1 to 100 mm. The separating liquid (L) is preferably a fluorinated fluid.

A multi stage process for the separation of bio-components from a waste stream containing Dried Distillers Grains with Solubles is disclosed. Targeted polymers are added to the source and separated streams prior to passing the streams through separation equipment including a rotary screen, a press, and a dissolved air floatation in which the waste stream is separated into a stream containing predominantly protein, a stream containing predominantly oil, a stream containing predominantly water and a stream that contains predominantly fibers.

The present invention discloses a process of disposal of tailings in piles stemming from the iron ore processing method, replacing dams, and comprising the steps of thickening the ultra-fine tailings, thickening the sandy tailings, mixing the tailings in the proportion of 80 to 90% by weight of sandy tailings and 10 to 20% by weight of ultra-fine tailings, addition of coagulant, addition of flocculant, filtering the mixture and piling the filtered tailings. Unlike traditional processes, this invention promotes an economically and technically feasible tailing disposal process that can be added to any conventional iron ore concentration plant without the need for any change in the process flowchart.
