Title: Process for the treatment of concentrates containing platinum group metals gold and silver
IPC: C01G55/00
Filed: 1976-01-29
Abstract: 1481295 Recovery of precious metals NATIONAL INSTITUTE FOR METALLURGY 29 Jan 1976 [29 Jan 1975] 03495/76 Heading C1A [Also in Division C7] Precious metals (defined as Pt. group, Au and Ag) are recovered from a concentrate by alloying the concentrate with Al, and leaching the alloy to produce a solution containing the precious metals. The alloy is preferably produced by melting the concentrate and Al powder at 1000 C or by an aluminothermic process by igniting a mixture of concentrate, Al powder and an oxide or sulphide (e.g. Fe 2 O 3  or FeS), at 1000 C (the oxide or sulphide may be omitted if already present in the concentrate). If the precious metal content of the concentrate is below 30 wt.%, the alloy may be formed by mixing the concentrate with C and CaO, roasting at 800 C, smelting with scrap iron in an arc furnace, removing the slag and adding Al scrap to form an Al-Fe-precious metal alloy. The alloy is initially leached with HCl or H 2 SO 4  to remove the Al and base metals, the residue being further leached under oxidizing conditions in HCl, using Cl 2  as the oxidant, to effect dissolution of the precious metals. If desired, the residue from the initial leaching step may be leached to dissolve Cu prior to the precious metal leach.

Abstract: 1,027,105. Lasers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 28, 1965 [Jan. 28, 1964], No. 3531/64. Heading H3B. In a Q-switched ruby laser in which circulated liquid nitrogen at a temperature of about minus 160‹ C. reduces the operating temperature of the ruby crystal 1, the cooling fluid is excluded from the light path by a stainless steel tube 10 which extends between the output end of the ruby and a rubber sleeve 11 abutting a Kerr cell 6. The optical cavity is formed by faceted end-reflecting surfaces of the ruby and a partially-transmitting mirror 8, the Kerr cell and a Nicol prism 7 being located in the cavity in such a sense as to be " crossed " with respect to incident plane polarized light. Operation is obtained by pulsing a helical Xenon flash tube 3 and subsequently pulsing the Kerr cell so that cavity reflections are permitted. The coolant liquid is derived from a source 4 and is contained by a dewar vessel 2. Heating coils 5 prevent temperature reduction of the flash tube, while a further heating coil, not shown, about the tube 10 prevents internal frosting. By segregating the coolant from the light path, misalignment of the optical cavity due to shimmering when an auto-collimator is used is prevented. The tube 10 is a push-fit on the end on the ruby. In a modification, a glass tube is used which abuts the ruby end. Also the faceted end of the active medium may be replaced by a plane surface and an external plane mirror.
