2013-7-23 · PHYSICOCHEMICAL CHARACTERIZATION OF COPPER SLAG AND ALTERNATIVES OF FRIENDLY ENVIRONMENTAL MANAGEMENT M. Sáncheza, M. Sudburyb,* a Director Escuela Ciencias de la Tierra Universidad Andres Bello Salvador Sanfuentes, Santiago, Chile b Director MPS Consulting, Oakville, Ontario, Canada (Received 14 August 2012; accepted 15 March 2013)
Copper slag is a by-product obtained during matte smelting and refining of copper. The common management options for copper slag are recycling, recovering of metal, production of value added
A novel hydrometallurgical method was developed to recycle valuable metals of Si, Fe and Cu from copper slag. The leaching rates of 98%, 99% and 91% for SiO2, Fe and Cu, respectively, were obtained under optimized parameters: solid-to-liquid ratio is 1:10; concentration of hydrochloric acid is 35%; the reaction time is 2 hours and at 80-90°C.
Apart from copper, these materials are used to produce by-products such as precious metals, nickel, tin, lead and zinc. 1. Multi-metal recycling with the Kayser Recycling System (KRS) at the Aurubis recycling center in Lünen: Copper scrap, electronic scrap and residues are used as input material in the Aurubis recycling center in Lünen.
Recycling of copper scrap greatly reduces natural resource exploration as an alternative source of copper metallurgy and has big advantage in investment, production cost and off-gas treatment, thus making the copper scrap smelting projects remunerative. However, due to the wide source range, the copper scrap is classified as per its grade, to be treated by different smelting process, which is

2014-2-28 · Three experiments are reduction of copper matte alone, reduction of copper matte in slag, and reduction of copper matte in alloy. Temperature is 1723 K. High-purity graphite powder (carbon content greater than 99.99%) was as reducing agent, and CaO (purity greater than 98.00%) was as
A larger up front investment will allow a continuous recycling operation. This gives the advantage of THE lowest cost per square foot for any given high performance blast abrasive. We have broken down recycling solutions into three levels: Level 1 Basic Recycling - Approximately $1000 to $5000 investment: Offers 1 to 3 reuses of the spent abrasive
2019-4-20 · Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other
