sulfur concentrate thickening
Simulation of an Alternative Direct Leaching Process for …
Alternatively, direct leaching processes may recover zinc from this undesired type of concentrate with high yields. In this work, we evaluate the sulfatation process (staged roasting process at lower temperature that favorites the oxidation of sulfides to sulfates) as an alternative and compare it with traditional direct leaching and roasting ...

Food thickening agents: Sources, chemistry, properties and applications
Thickening agents are one of the major food ingredients that significantly control the textural properties of various food products (Clegg, 1995).They control moisture and provide structure, flow, stability, and eating qualities to food products (Imeson, 2009).The rheological properties of thickeners in any solution depends on various …

Concentrate Dewatering & Thickening
The size of a concentrate thickener is determined by the tonnage of solid material to be dewatered, the amount of water in the pulp, and the settling rate of the solids. In the absence of specific data, it is usual, for the purposes of rough calculations, to allow 10-15 sq. ft. of tank area per ton of dry concentrate produced per 24 hours.

Zinc Extraction; In Brief Review from Past to Present
Combustion of the sulfur contained in the concentrate with air at temperatures above 900 °C produces SO 2, which is subsequently converted to sulfuric acid in a recovery unit. In the roasting operation, much of the Zn is converted to ZnO, which dissolves readily in the dilute H 2 SO 4.
