Sorry, preview is currently unavailable. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. Keywords: Copper smelting, Slags, Microstructure, Thermodynamic modelling. Two different types of Concrete Grade Blends of copper slag with Portland cement generally possess properties equivalent to Portland cement containing fly ash, but very different to the silica fume incorporation. Copper slag is used as a building material, formed into blocks. which is almost similar to the bulk density. ABSTRACT Effective extraction of copper from sulphide ores requires careful operation of a copper smelter, which in turn depends very much on the chemistry of the feed and the resulting slag and matte. Slag properties are important since they: (i) have a decisive effect on both process control and on the quality of the product and E. S – 2 (ii) good quality property data are needed to develop reliable mathematical models of the process and to optimise the efficiency of the process and quality control. 200 sieve) in size. The average composition of primary copper slag corresponds to 30–40 % iron, 35-40% silica, less than 10 % of alumina and calcium oxide and copper content is around 1 %Cu, similar to the ore mined. The slag properties, particularly slag viscosity and electric conductivity, play very important roles in copper concentrate smelting in the Teniente Converter and in slag cleaning in the electric furnace. Copper and its alloys, such as brass, are used for jewellery and ornaments. increasing copper loses in the discard slag.

The results of laboratory tests on this slag have been compared with the representative values obtained for sands. When copper liquid settles down in the smelter due to its higher density, the smears of copper slag remaining on the surface (also in liquid … Herein, an innovative technology has been developed to transform fayalite to magnetite and to induce the grain growth of copper matte and magnetite by modifying the molten copper slag. Non-magnetic. The optimum proportion of copper slag is found up to 100% CS for all the strength and durability parameters in HSC. endstream endobj 32 0 obj <>stream Copper is non-magnetic and non-sparking.
