Method for Treatment of Solid Starting Material

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a process for treating solid materials that contain metals or metal compounds, such as ores, residues, sludges, slags, and ashes from combustion plants. The method involves washing the material with an oxidizing acid to dissolve the metals, which can then be separated and recovered from the solution.

Use CasesContent extracted from patent full text and abstract with AI.

• Recycling metals from industrial waste such as slags and filter dusts
• Extracting valuable metals from mined ores
