A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility.

This invention relates to a process for recovering value metals from sulphide ore, including steps of crushing ore in a primary crusher (14) to a size of about 40 cm and less, passing the crushed ore through one or more of the following pre-beneficiation processes such as bulk sorting (16) and screening (20) followed by coarse floatation (46/50), or gravity separation or magnetic separation. A waste stream (54) from the pre-beneficiation process/es with a particle size greater than 100 μm is stacked in a heap (26) and subjected to a heap leach. This integrated process utilises the pre-beneficiation techniques best suited to the characteristics of a particular orebody; and during the pre-beneficiation simultaneously creating a low grade stream that yields significantly higher recoveries than achievable by normal heap leaching of low grade run of mine ore.

A method of grading and washing sand including the steps of removing oversize material from a feed material to which water is added on a first grading screen, whereby the oversize material passes over a downstream end of an apertured deck of the first grading screen, undersize material and water passing through the apertured deck being collected in a sump of the first grading screen before being passed onto an apertured deck of a second grading screen having apertures of a smaller size than those of the deck of the first grading screen, oversize material passing over a downstream end of the second grading screen, pumping water and undersize material from a sump of the second grading screen to a washing stage to remove fine contaminants therefrom.

A device for sorting particulate material includes a main conveyor belt, a separation screen, a graded material conveyor, and an oversize material conveyor. The separation screen is configured to separate the material into a first portion and a second portion with a larger average particle diameter than the first portion. The graded material conveyor is positioned below the separation screen to receive the first portion of the material, and the oversize material conveyor is positioned at an end of the separation screen to receive the second portion of the material.

Disclosed are a wet sorting process for a waste lithium battery and application thereof, which belong to the field of battery material recycling. The wet sorting process includes the following steps of: carrying out wet ball milling on a sorting material of a waste lithium battery to obtain a ball-milled product screening the ball-milled product to obtain a coarse-grained screened material, a medium-grained screened material and a fine-grained screened material, carrying out wet ball milling, screening, magnetic separation and table concentration on the medium-grained screened material to obtain copper, aluminum and a steel shell and carrying out flotation, magnetic separation and table concentration on the fine-grained screened material to obtain cathode material powder, graphite, copper and aluminum.
