A method for producing a powdered starting material, which is provided for production of rare earth magnets, including the following steps: pulverizing an alloy, including at least one rare earth metal, wherein a powdered intermediate product is formed from the alloy including at least one rare earth metal, and carrying out at least one classification aimed at particle size and/or density for the powdered intermediate product, wherein a fraction of the powdered intermediate product, which is formed by means of the at least one classification, for fabrication of rare earth magnets. Furthermore, at least one dynamic classifier is provided, implementing at least one classification directed at particle size and/or density for the powdered intermediate product and thereby separates the fraction from the powdered intermediate product, which forms the starting material provided for manufacturing rare earth magnets.

THIS invention relates to a process for the enhanced recovery of chromite and platinum group metals (PGMs) from a mixed chromite/PGM ore. Ore is ground 12, classified 14, to produce a coarse fraction and a fine fraction 36. The coarse fraction is subjected to gravity separation 16 and coarse particle flotation 20 to obtain a chrome concentrate and a PGM concentrate. The fine fraction 36 and PGM concentrate are ground 28, and subjected to conventional flotation 30 to obtain a PGM concentrate product 32. The benefits of this novel configuration of gravity concentration and coarse flotation technologies, as applied to both chromite and PGM recovery, are higher recoveries of chromite in a saleable concentrate, higher recoveries of PGMs and base metals, and lower chromite content in the PGM concentrate.

A chute apparatus is comprised of a guide member, an arched member, and a floor member. The guide member guides an object entering the chute apparatus. The arched member receives the object from the guide member and redirects the object toward an exit port of the chute apparatus. The floor member receives the object from the arched member and directs the object toward the exit port of the chute apparatus. It is contemplated that the object may comprise a fruit, such as a berry or the like.
