Title: Nickel laterite treatment process for the production of nhp
Inventor: SMITH VINCENT
IPC: C22B23/00
Filed: 2014-12-10
Abstract: It is a laterite treatment process to extract nickel and other valuable constituents from limonite and saprolite ores to produce a saleable hydroxide product white the corresponding waste effluents are treated to suit environmental disposal standards. The leaching section takes advantage of the iron and magnesium content of the ore to induce in-process hydrolysis that regenerates acid, thereby minimizing overall acid requirement. Leaching is performed in two stages composed of an atmospheric tank leaching stage and a medium-pressure autoclave leaching stage. The high iron, low magnesium size fraction of the ore is leached in the atmospheric tank leaching stage, while the high magnesium, low iron size fraction is leached in the autoclave leaching stage. The pregnant leach solution undergoes a solution purification stage in the form of ion exchange, solvent extraction, or selective precipitation. The purified pregnant leach solution is then added with a precipitating agent to increase its pH thereby precipitating nickel in the form of nickel hydroxide. Waste effluents such as solid leach residue and barren solutions are treated by the addition of limestone and lime slurries to meet environmental standards for waste disposal.

A unit 20, comprising a turbine which drives a blower, Fig. 2 (not shown), is supplied with atmospheric air through pipe 21' via filter 15', some of the air driving the turbine and then exhausting through pipe 23' to a low pressure region of an I. C. engine induction system, whilst the rest of the air is pumped by the blower through pipe 22' to the engine exhaust system - either to the exhaust manifold, or to the exhaust pipe, or to an exhaust afterburner 50. In the latter case, if the temperature in the afterburner exceeds a certain value, a temperature - responsive valve, Fig. 8 (not shown), opens to put pipes 21" and 29 into communication so that some of the air passing through the filter 15' by-passes the unit 20 and is supplied to the pipe 23' thus reducing the pressure differential across the turbine and therefore its speed, reducing the air supply to the afterburner, and weakening the mixture supplied to the cylinders. The air supply to the turbine part of unit 20 may be restricted, or a metering orifice may be provided in a fitting 63 between the pipe 23' and the unit 20 downstream of the junction with pipe 29, Fig. 7 (not shown).

Abstract: 1284521 Electro-photography XEROX CORP 2 Jan 1970 [13 Jan 1969] 239/70 Heading G2H An electro-sensitive non-fracture image is formed in an electro photo-sensitive imaging layer by simultaneous application of a uniform electric field and image-wise electromagnetic radiation followed by discharging the layer (before removing a receiver sheet, if present), whereafter a corresponding photographic image or negative thereof is transferred to a receiver sheet by fracture of the imaging layer while in cohesively weak state under the action of a second uniform electric field (of a strength the same as or different from that of the first field) and in the absence of electromagnetic radiation. The electro-sensitive image may be formed while the imaging layer is or is not cohesively weak. The cohesively weak state may be produced by the application of heat or a solvent or swelling agent to the imaging layer. The latter may, for example comprise a mixture of micro-crystalline wax and polythene as activatable binder for the electro photo-sensitive material. A liquid activator may, for example, be an aliphatic hydrocarbon fraction. Donor and receiver sheets may, for example, be of polyethylene terephthalate. An electro photo-sensitive coating layer 201, Fig.2, may be applied to a donor sheet 203, a sandwich of the coated sheet 203 and a receiver sheet 205 placed between a NESA glass plate 215 and black conducting paper, and a non-fracture image formed. A fracture image may then be formed by removing a receiver sheet 307, Fig.3, while applying an electric field to the imaging layer in a cohesively weak state.
