Geochemical Characterization of Tailings, Kylylahti Cu-Co,

Key words: Geochemical characterization, tailings, supernatant, acid generation, PHREEQC, Finland. Introduction The proposed Kylylahti Cu-Co project, located in south-eastern Finland, is an ‘Outokumpu style’ deposit containing copper-cobalt-zinc-nickel-gold. The proposed mine will sell copper-gold concentrate and nickel-cobalt hydroxide. Ore will be processed via conventional crushing and ball millReuse of copper slag in high-strength building ceramics,,15/08/2020· The copper slag used in this study was from Boliden Oy, Finland, who produce about 400,000 tonnes copper slag/ year. The sample was received in milled state from the company. The spodumene tailings (quartz-feldspar sand, QFS) used in this study was obtained from Keliber Oy, Finland. The kaolin used was from Sigma Aldrich.

Box 96, FI-02151, Espoo, Finland Abstract The present study valorized Finnish mining tailings waste to identify opportunities forCopper Tailing - an overview | ScienceDirect Topics,Extraction of copper from its ore in copper industries produces two types of waste named as copper slag and copper tailings. The copper slag is produced during the process of smelting for sulphide ore and collected as the material that floats on the top of the molten copper in a furnace. This material ultimately turned into glassy solid after cooling and discarded as waste in dump yards. After suitable crushing, this waste can be utilized as filler in asphalt mixes.

The World's 20 Largest Copper Mines - ThoughtCo

25/11/2019· The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine. The high costs of financing a major mine are,Outotec to deliver Finland tailings plant - Mining,Outotec to deliver Finland tailings plant .
