Indium prices vary by purity level according to the number of mines. For 99.97 or 99.99% pure indium Meta/Bu//etm magazine s free-market prices ranged from 160 to 190/kg in 1993. Prices have trended downward since 1988. This, coupled with the fact that consumption increased during this period, is evidence that supply is ahead of demand. The most notable production increases have occurred at Indium Corp. of America, Nippon Mining Co. Ltd., Cominco Ltd., and Metaleurop S.A. The largest increase was made by Indium Corp. A 30-t increase was announced in 1988 in 1993 Indium Corp. announced plans to increase production by another 30 t to be phased in with demand, bringing the company s actual and planned increases to 60 metric tons over the 1988 level. [Pg.80]

Electrolytic Eefming. Electrolytic refining (26,27), used by Cominco Ltd. (Trad, B.C., Canada) and Cerro de Pasco Corp. (La Oroya, Pern), as weU as by several refineries in Europe and Japan, removes impurities in one step as slimes. The impurities must then be separated and purified. Before the development of the Betterton-KroU process, electrolytic refining was the only practical method of reducing bismuth to the required concentrations. [Pg.47]

Thus, roasting is avoided. The process, especially amenable to high iron and copper concentrates, has been installed by Cominco, Ltd. (44) at Trad, B.C., Canada, and will be installed at the Kidd Creek Mines, Ltd., plant at Timmins, Ontario. [Pg.402]

Alison Dickson is a metallurgist at Polaris, the world s northernmost mine. Polaris is located on Little Cornwallis Island in Nunavut. It is a lead and zinc mine, operated by Cominco Ltd., the world s largest producer of zinc concentrate. [Pg.77]

Although means are available for controlling the bulk of the emissions from the conventional lead and zinc smelters, new processes being developed offer greater economy as well as better emission control (9,10). Cominco Ltd. recently announced the development of a new process to replace the conventional lead smelting process with its sintering plants and blast furnaces (39). [Pg.15]

The physical properties of the slag and bullion at the feed temperature of 1150 ° C are listed in Table I. Relationships for the temperature dependence of density and viscosity were developed from the plant data provided by Cominco Ltd. Because of a lack of information, the magnetic permeabilities of both slag and bullion were taken to be equal to the value for free space. [Pg.698]

The authors are very grateful to Dr. J. Dableh for his help in developing the electrical model of the furnace. The many fruitful discussions with Dr. G.G. Richards and Mr. A. Hall of Cominco Ltd. on all aspects of the electric furnace operation are greatly predated. The financial support of CANMET and Cominco Ltd. for this project is also gratefiilly acknowledged. Finally, the authors would like to thank Cominco and Snamprogetti for reviewing the final paper. [Pg.706]

Spool system - Cominco. The spool or sloping-tangent contact bar was developed in the 1970s by Cominco Ltd and utilizes a contact bar similar to that shown in Figure 4. This bar is claimed to provide excellent electrical contact via the notched portion of the header bars [5]. In theory this arrangement results in each electrode having four points of contact with the intercell contact bar. [Pg.179]
