In 1986 Britannia Refined Metals (Northfleet, U.K.) introduced technology for the treatment of Parkes cmst, a triple alloy of Ag, Zn, Pb, which by 1992 had been adopted by seven lead refineries (22). The technology consists of a three-stage process in which the silver-rich cmst is first Hquated to reduce its lead content, then placed in a sealed furnace where the 2inc is removed by vacuum distillation and, finally, the silver—lead metal is treated in a bottom blown oxygen cupel (BBOC) to produce a Htharge slag and dorn metal. 

Precision dupHcation, durabiHty, and metallic beauty have made antimonial alloys, such as pewter and britannia metal, desirable for decorative castings. Several different tin—base and lead-base antimony alloys are used in the jewelry industry. These alloys are typically cast in mbber or siHcone molds. 

Gelatin B from cow bone was supplied by Britannia Lab Argentine with isoelectric point of 5.10. Gelatin was dried and sealed in zip plastic bags and then kept in desiccators. Finally, gelatin was dissolved in distilled water preparing a solution of 0.25, 0.5, 0.75 and 1% (wt.).

Based on the pilot-scale operation at the Britannia Mine, the vendor estimated the full-scale capital costs to be 2.5 million. Zinc and copper sulfates in the processed waste may be sold to smelters. The sale of these metals was estimated to produce a potential net operating profit for the plant of 130,000 per year (D16056F, p. 38).
