摘要： The present disclosure relates to the field of mineral processing and separation, and in particular, to an underground coal hypergravity field separation system and a separation process. The separation system includes a grading hydrocyclone group, hypergravity field separators, feeding pumps, and conveying pumps. Coal collected underground is graded through a grading hydrocyclone first, then is fed into the hypergravity field separators for separation, and finally, is conveyed to a next link for dehydration through the conveying pumps. The separation system of the present disclosure has less supporting equipment, small floor area, and no complex pipeline, and is suitable for a downhole operation. In addition, the hypergravity field separators can provide a high-strength centrifugal acceleration, which can realize rapid separation of coal gangue particles in a radial direction and a tangential direction, and realize effective separation of fine coal gangue particles.

摘要： Described is a conveyor sluice system useful for mining fine particles of target minerals, such as gold, that are difficult to collect and are therefore often discarded. Several conveyor sluice arrangements discussed herein use a textured belt that is wrapped around head and tail pulley rollers. Post hydrocyclone aggregate distributor feeds conveyor sluice slurry onto the textured belt near the head pulley roller. As the conveyor sluice slurry flows down the textured belt surface, concentrated aggregate (rich in target heavy minerals) settles and gets trapped in the belt texture. At least one belt cleaning rinse nozzle aims rinse water at the textured outer surface and sprays the concentrated aggregate out from the belt texture. A concentrate launder collects the rinsed off concentrated aggregate and pumps it to a finishing table where the target minerals are separated and collected.

摘要： This application discloses a separator for separating and recovering materials from a waste stream. The separator has a cyclone having a top section and a bottom section, an impeller within the cyclone, a media inlet for accepting a flow of media or a pulsating flow of the media operatively connected to the impeller in which media or fluid flows through the impeller into the separator; a first discharge passage for a collecting a light fraction, and a second discharge passage for collecting a heavy fraction.

摘要： A system and method for separating two or more materials, such as a solid from a liquid, or a solid from a slurry, are provided. An exemplary system and method for separating drill cuttings from drilling fluids are provided, as well as a system and method of processing such separated drill cuttings. In another implementation, a system and method is provided for separating gold (or another mineral, element, or solid) from a slurry or liquid that includes mining cuttings.

摘要： A slurry handling apparatus includes at least one reception hopper includes a base, a rear wall and opposing side walls, and an opening provided in the base. Slurry delivered into the reception hopper from a tanker can pass through the opening in the base, and a respective first dewatering screen having an apertured screening deck is located beneath the at least one reception hopper so that slurry passing through the opening is delivered onto the deck of the respective screen, with undersize material and water passing through the apertures of the deck to be received within a sump, and with oversize material passing over the deck to be discharged from a downstream end of the deck.

摘要： An apparatus for classifying fine particles in slurry provides a sharp particle size distribution with few mixed coarse particles and high classification accuracy.
The apparatus includes a rotor (15) including classification chambers (17) between blades (16) radially arranged at circumferentially regular intervals, and classifies particles so that a classified particle size is constant in an entire radial region from an outer periphery to an inner periphery of the classification chamber. The blade (16) of the rotor has a circumferential thickness t(d) increasing toward the outer periphery, and the classification chamber (17) has a width increasing toward the inner periphery.-

摘要： A cyclonic separation and materials processing method and system is presented in which materials entry at one end and which is arranged so that the materials that enter will be given a tangential velocity component as they enter. Specific embodiments include a three-dimensional sorting system with the use of an outward centrifugal motion and up/down (or vertical) motion flow of water or other media, which can be thought of as “a three-dimensional separation”.

摘要： An apparatus for washing and grading sand includes a first vibrating screen having a deck arranged to receive a feed material. Oversize material passes over the deck of the first vibrating screen for collection as a first product, and undersize material and water are collected in a sump of the first vibrating screen before being pumped to a hydrocyclone. A second vibrating screen receives an underflow from the hydrocyclone upon a deck thereof, with oversize material passing over the deck of the second vibrating screen for collection as a second product. An overflow from the hydrocyclone passes into a settling tank, and a water storage reservoir receives water overflowing from the settling tank while sludge is collected and removed from a lower end of the settling tank. Water is passed from the water storage reservoir to the first and second vibrating screens to wash and fluidise material thereon.

摘要： A process for refining sand for use as frac sand includes the steps of passing the sand through a first fines separation stage to remove fine particles of contaminant from the sand, reducing the water content of the sand (such as to less than 20%), passing the sand into an attrition scrubber unit containing moving blades to delaminate clay and other contaminants from the sand grains, passing the sand from the attrition scrubber unit through a second fines separation stage to separate fine contaminants from the sand, and dewatering the resulting sand product in a further dewatering stage.
