摘要： An apparatus for treating, in particular purifying or degassing, molten metal (40), comprising a component (10) exposable to molten metal to be treated and means (13) for imparting a rotary motion to the molten metal (40) about a substantially vertical axis. The apparatus is so arranged that during use at least part of a wear-exposed surface of the component (10) is temporarily or permanently in contact with molten metal (40), the contacting molten metal being in motion relative to the wear-exposed surface. The wear-exposed surface is coated with a slurry-applied protective coating (18A,18B) of refractory material in a heat stable binder, in particular an inorganic colloidal and/or polymeric binder, protecting the wear-exposed surface against erosion, oxidation and corrosion.

摘要： Process for the dissolution of silver and gold from ores and concentrates in a strong chloride solution where the Eh is maintained above a value of 750 m.v. and preferably above a value of 850 m.v. This process may include the additional step of removing excess chlorine from solution by blowing the solution with air and conducting the air and chlorine gas to another vessel where the chlorine is reacted with fresh incoming ore or concentrate. Subsequently the substantially chlorine free solution is contacted with a solid reductant to produce silver or gold precipitate. The above process is particularly suitable for operation in an electrochemical diaphragm cell.

On met ensuite en contact la solution exempte de chlore avec un agent réducteur solide pour produire un précipité d'argent ou d'or. Le procédé ci-décrit convient particulièrement à l'utilisation dans une cellule électrochimique à diaphragme.

b) sulphating (4) in an oxidising environment to convert non-ferrous metals to sulphate and/or oxysulphate form;
c) leaching (5) in water or a weak aqueous solution of sulphuric acid to recover any copper, nickel, cobalt, zinc, uranium and molybdenum present, and at least part of the silver present;
d) treating (10) the leaching residue from stage c), for example, by leaching in a solution of chloride of an alkali metal or an earth metal, or smelting said residue while slagging any iron content therein to recover the lead content and any silver remaining.

摘要： A method for recovering ruthenium from waste catalyst of aluminum oxide loaded with ruthenium comprises the following steps: drying, roasting and cooling the waste catalyst of aluminum oxide loaded with ruthenium; grinding into black powder containing ruthenium oxide; placing the black powder into a fluid bed reactor, introducing hydrogen and performing reduction reaction, thereby obtaining metal Ru; introducing a mixed gas of oxygen and ozone into the fluid bed reactor and oxidizing the waste catalyst, thereby obtaining RuO 4 gas; introducing the RuO 4 gas into sufficient hydrochloric solution to dissolve the RuO 4 gas, thereby obtaining an H 3 RuCl 6 solution; adding excessive oxidant into the H 3 RuCl 6 solution and promoting the H 3 RuCl 6 to be fully oxidized, thereby generating hexachloro (IV) ruthenium acid; adding excessive NH 4 Cl, reacting, filtering and cleaning filter cake, thereby obtaining an ammonium hexachloro (IV) ruthenium solid; and finally, performing hydrogen reduction treatment on the ammonium hexachloro (IV) ruthenium solid, thereby obtaining the metal ruthenium. The method is simple in operation, low in cost, short in recovering period and high in recovery ratio.

摘要： Provided is a process for the comprehensive recovery of metal cobalt, ruthenium and aluminum from a waste catalyst Co-Ru/Al 2 O 3 in a Fischer-Tropsch synthesis. First, a waste catalyst is subjected to hydrocarbon removal, and reduction treatment, to effectively separate a cobalt slag in an alkali fusion step, and then the cobalt slag is subjected to the steps of acid leaching, cobalt precipitation with oxalic acid or ammonium oxalate, reduction of cobalt oxalate, dissolution of metal cobalt with nitric acid, etc., to obtain Co(N0 3 ) 2 ·6H 2 O. A ruthenate which is dissolved by steps such as alkali fusion, and leaching with deionized water, is subjected to the steps of reduction with ethanol, dissolution with concentrated hydrochloric acid, distillation under reduced pressure, etc., to obtain a ²-RuCl 3 ·xH 2 O product with a high purity. Aluminum hydroxide is prepared from a meta-aluminate solution by CO 2 carbonation, by controlling the parameters such as reaction temperature, flow rate of CO 2 , pH value at the end point of the reaction, etc., and the aluminum hydroxide is calcined to obtain aluminum oxide with a product quality achieving the quality requirements of first-class aluminum oxide in the Chinese national standard. The resulting product has a high yield, wherein cobalt is ‰¥ 97%, ruthenium is ‰¥ 95%, and aluminum is ‰¥ 92%.
