Abstract: A vertical roller mill has grinding rollers which roll over a grinding path of a rotatable grinding table, and a surrounding nozzle ring separation area for conveying and separating gas. A coarse fraction of ground material is entrained in gas upwards in ducts from a location that is below, at, or above the nozzle ring separation area and is transported into an entry to a material separator located above the grinding table.

Abstract: A method of improving metal leach kinetics and recovery during atmospheric or substantially atmospheric leaching of a metal sulfide is disclosed. In some embodiments, the method may comprise the steps of: (a) producing a metal sulfide flotation concentrate; (b) processing the metal sulfide concentrate in a reductive activation circuit that operates at a first redox potential, to produce a reductively-activated metal sulfide concentrate; and, (c) subsequently processing the activated metal sulfide concentrate in an oxidative leach circuit to extract metal values. In some disclosed embodiments, reductive activation steps may be employed prior to oxidative leaching steps (including heap leap leaching or bio-leaching steps). In some embodiments, physico-chemical processing steps may be employed during reductive activation and/or oxidative leaching. Systems for practicing the aforementioned methods are also disclosed.

Abstract: The present invention is directed to a method of continuously calcining a limestone particle mix comprising a fine fraction of limestone particles and a coarser fraction of limestone particles. The limestone particles heat treated in a flash calciner in which the mixture is entrained and heated in process gas for an amount of time sufficient to fully calcine the fine fraction but not the coarser fraction. The process gas is separated from the heated limestone mixture. The mixture is directed to a retention vessel in which the mixture is retained for an amount of time sufficient to fully calcine the coarser fraction utilizing the process heat present in the limestone mixture. No external heat needs to be added to the retention vessel during the retention step to promote calcination.
