Title: Production of nickel from nickel bearing materials
IPC: C22B23/02
Filed: 1971-04-19
Abstract: 1334170 Extracting nickel and nickel alloys KAISER ALUMINUM & CHEMICAL CORP 19 April 1971 [26 March 1970] 22648/71 Heading C7D Nickel is extracted from material containing also less noble metals including cobalt and iron in a counter current process in a furnace having zones as shown in the Fig. in which an underlying metal layer progressively increasing in nickel content flows towards the metal tapping end while a slag of progressively decreasing nickel content flows to the slag tapping end. Cobalt, iron and a considerable amount of nickel are oxidized and transferred from the metal phase to the slag phase at the metal purification zone and almost all of the nickel and some less noble metal is reduced from the slag phase in the slag treating zone. The oxidising agents may be gaseous such as oxygen, carbondioxide, steam, air, or solid such as nickel oxide. The reducing agent may be gaseous such as hydrogen, carbon monoxide or gaseous or liquid hydrocarbons or molten iron or carbon. Where the material from which nickel is to be extracted is an alloy containing iron and nickel, this may be used as reducing agent. In order to minimise contamination of the metal product with cobalt, a cobalt-nickel alloy may be withdrawn from the metal phase in an intermediate zone, e.g. an alloy having a cobalt content of at least 10 wt per cent, and preferably having a colbalt: nickel ratio of 1:1.

Abstract: 1304717 Treatment of fibres; -finishes UGINE KUHLMANN 13 May 1970 [20 May 1969] 23216/70 Headings D1F and D1P A process for the treatment of textile fibres before carding and combing is characterised in that the treatment is effected in the presence of a reaction product obtained from a compound containing at least one nitrogen atom, and at least one active hydrogen atom and two alkylene oxides, of which one is ethylene oxide containing two carbon atoms, while the other contains at least three carbon atoms. The compound is preferably dissolved in water and applied thus. The compound may be formed in several ways, by reacting the nitrogen and hydrogen containing compound with the two alkylene oxides; (a) the compound in question may first be reacted with an alkylene oxide having at least three carbon atoms and the resulting product reacted with ethylene oxide; (b) the compound in question may first be reacted with ethylene oxide, after which an alkylene oxide with at least three carbon atoms is fixed by addition on the product obtained; the compound in question may be reacted (c) before or (d) after addition of ethylene oxide, with a mixture of alkylene oxides containing at least 40% (by weight) of alkylene oxides containing at least 3 carbon atoms and at most 60% (by weight) of ethylene oxide. Especially suitable compounds containing the nitrogen and hydrogen atoms are polyalkylene polyamines, e.g. propylene diamines; diethylene triamines; tetraethylene pentamines. Other compounds are listed in the specification. Further additives may be incorporated to improve the feel and anti-static properties of the textile fibres e.g. sulphated derivatives of an ethoxylated fatty alcohol or ethoxylated alkyl phenol; phosphoric acid esters of a fatty alcohol or ethoxylated fatty alcohol; polypropylene glycol on which ethylene oxide has reacted; or a polyethylene glycol ester of a resinous acid. The fibres so treated may be wool, rayon or synthetic e.g. acrylic fibres.
