{{#badges:CoalSwarm}} Coal sludge, also known as slurry, is the liquid coal waste produced by mining activities.After mining, coal is crushed and washed to remove the surrounding soil and rock. The washing process generates huge amounts of liquid waste, and the mining process itself produces millions of tons of solid waste.
obtained 2+concentrated solution containing 1000 mg/L Ni ions produced pure metallic nickel by electrodeposition on the copper cathodes. The proposed technology offers relevant metal companies the opportunity for significant cost benefit through metal recovery from industrial waste which would otherwise result in landfill.
