Abstract.Lead: Secondary Lead Smelter eTool - Definitions,Blast furnace - Blast furnaces are reduction furnaces that produce hard or antimonial lead containing about 10% antimony. Pretreated scrap metal, rerun slag, scrap iron coke, recycled dross, flue dust, and limestone are used as charge materials to the blast furnace.US1950387A - Slag formation and reduction in lead,,In addition, many of these impurities appreciably interfere with desilverization and arsenic, tin and antimony are probably the most troublesome in this respect. For their removal the impure bullion is charged to a softening furnace whereby oxidation these elements form drosses or slags and, with some lead, are skimmed from the bath.

Abstract Cleaning of high antimony smelting slag from an oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. The effects of added CaO, mass ratio of coal (experimental) to coal (theoretical) (x) and the slag type on the reduction pro-cedure were considered. The contents of Sb and Au were investigated.Investigation into Oxygen-Enriched Bottom-Blown Stibnite,,pilot test of 100 days, and a cleaning experiment of high-antimony molten slag from oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. Autogenous smelting was achieved without adding any other fuel, which guaranteed the fea-sibility and advantage of oxygen-enriched bottom-blown stibnite.MetallurgicalFurnaces - vscht,Metallurgical Furnaces 1 MetallurgicalFurnaces For other industrial reactors and their applications, see →Stirred-Tanc and Loop Reactors, →Tubular,2 Metallurgical Furnaces 1.RotaryKilns A rotary kiln is an inclined, rotating cylindri-,In iron ore reduction, low-iron alu-minaormagnesium–spinelbricksarerequired [23],[24,
