Lead Recovery from Solid Residues of Copper Industry Using Triethylenetetramine Solution
Industrial processing of mineral ores and concentrates generates large amounts of solid residues, which can be landfilled or further processed to recover selected elements depending on its economical profitability. Pressure leaching is a technology enabling high recovery of base metals like copper a...
