Abstract: Important variables which influence the efficiency of a hydrodynamic separation of dense materials using a hydrocyclone are the dynamic viscosity at the inflow of the hydrocyclone and the number of passes through the hydrocyclone. According to the invention, the method and the device allow a control of the viscosity in the hydrocyclone as well as the number of passes through the hydrocyclone when separating dense materials from a slurry in conjunction with an anaerobic fermentation of the constituents of the slurry which can be fermented. By fermenting the constituents of the slurry which can be fermented, the content of a fermentation reactor has a lower viscosity than the slurry being fed. The viscosity in the inflow of the hydrocyclone is set by means of a controlled return flow from a fermentation reactor, and the number of passes is set by a controlled return flow from the outflow of the hydrocyclone. The slurry is pumped into a return flow from the fermentation reactor. The viscosity in the inflow of the hydrocyclone is controlled by the throughput of the return pump on the basis of the content of solids of the slurry. The number of passes through the hydrocyclone is controlled via the ratio of the feed of the hydrocyclone to the feed of the fermentation reactor from which dense materials are removed. Because the process of diluting the slurry with the content of the fermentation reactor does not have an influence on the hydraulic dwell time in the fermentation reactor, the fermentation reactor can be designed for a smaller accumulation of slurry.

The absorptive article quick decomposition system is mainly constructed by a cutting separating module, a liquid proof reclaimed material filtering module, a recycling module, a salt slurry processing module, a plastic raw material manufacturing module, a hygroscopic raw material manufacturing module, and a fluff fiber raw material manufacturing module. The absorptive article quick decomposition system and operating method make the recycled absorbent articles become possible to be decomposed into plastic raw materials, hygroscopic raw materials and fluff fiber raw materials. In addition, organic pollutants on absorbent articles are decomposed. The purified and treated water thus recovered and the recycling is realized for good.

Abstract: The invention relates to a device for continuously sorting a particulate stream, comprising: a) a conveyor (1) for conveying the particulate stream to a separation device, b) a sieve (7) for separating the particulate stream according to size, characterized in that it further comprises c) a per-sieve (3) comprising elongated sieve openings located between the convey or outlet and the sieve d) and a mechanical impact device for providing mechanical impacts to the pre-sieve (3). The pre-sieve allows to separate elongated objects like threads or wires form the particulate stream which would otherwise clog or block subsequent separation devices including the sieve.

Abstract: Disclosed are a method for recycling an iron ore tailing and use thereof. The method includes: 1) conditioning the iron ore tailing to obtain a first slurry, adding water glass and a sodium oleate-associated substance sequentially to the first slurry to obtain a first mixture, and subjecting the first mixture to first flotation to obtain a mixed flotation foam product and a mixed flotation grit; 2) filtering the mixed flotation foam product to obtain a solid, drying, roasting at 400° C. to 650° C., and grinding to obtain a ground product; and 3) conditioning the ground product to obtain a second slurry, adding sodium sulfide, water glass, sodium alginate, hydroxamic acid, and terpenic oil sequentially to the second slurry to obtain a second mixture, and subjecting the second mixture to second flotation to obtain a rare earth concentrate and a rare earth tailing.

Abstract: A spent and/or decommissioned accumulator treatment plant and process, wherein a plurality of objects originating from separate waste collection of spent and/or decommissioned accumulators, nominally comprising lead-acid accumulators and accumulators and objects of a different type, are subject to an X-ray scan. If an analysis of the X-ray scan indicates that an object is not a lead-acid accumulator, and in particular is a lithium-ion battery or accumulator, it is deviated out of the treatment workflow, that comprises grinding the objects and separating lead from other materials.

Abstract: A portable, modular mini mining jig can be configured as a single-stage jig with one or multiple jig cells, or as a multistage jig with one or multiple jig cells per stage. Due to the modular nature of the mini jig components, any number of jig cells and stages are possible. Adding jig cells and stages increases the throughput and capacity of the system, which increases efficiency.
