Water consumption in Chile's vast copper mining industry is set to rise 66 per cent by 2025, with companies increasingly turning to seawater to meet mine demand, a study by state copper commission Cochilco showed on Tuesday.
This study investigated the different methodologies for the treatment of mining effluents and their use in the Chilean mining industry. The technologies compared were selected by the International Network for Acid Prevention as the best available techniques to treat sulfates the most important copper mining wastewater contaminants.
majority of emissions can be found in discharged mine water. As mine water accumulates when the water level overflows the depth of an open pit surface mine or an underground mine, the water must be pumped or drained out of the mine to ensure safety and stability. Depending on the water availability and quality, it may be reused for

Jun 15, 2012· Mining waste dumped into water bodies totals more than 180 million metric tons (400 billion pounds) each year, and nine of the world's largest mining companies use this disposal technique, according to the report.
essential part of the copper mining industry regardless of the ore type being extracted. In open cast mining, water is necessary for dust suppression, ore processing, washing machinery and for domestic consumption. It is highly important that mining operations have access to a consistent water supply with adequate quality to ensure continual

Sep 26, 2019· Chile, the world's largest copper producer and global source of lithium, is just one of many jurisdictions where miners will soon have to deal with broader water use restrictions.
Copper mining requires lots of water to turn oxide ores into cathodes. However, due to environmental concerns, miners are facing increasing pressure to reduce their fresh water consumption.
Water is a critical resource for mining and metal production processes, and the copper industry is very aware of the impact of its operations on the environment, including water consumption. Copper mining is often located in areas exposed to lack of water, which makes saving water a necessity.
Water use in coal mining varies according to the method of mining, the equipment used, and the availability of water. Underground coal mines in West ia rely on the use of water for cooling the cutting surfaces of mining ma chinery and for inhibiting frictioninduced ig nition of coal fines or gas. Surface mines in the
Throughout the last decade, about 41% of the EU's annual copper use came from recycled sources. Future innovative policies and technologies should continue to contribute to resource efficiency in both the mining of "primary" copper and the recycling of "secondary" copper metals. Mine production is vital to meet future demand
