Recovering antimony from secondary sources is increasingly important to ensure a sustainable and secure supply of this critical metal. Industrial residues, waste materials, and by-products offer opportunities for recycling and reprocessing, reducing economic dependence on primary ores. This paper reviews potential waste streams and processing methods for achieving high-yield antimony recovery.

Technological, technical and strategic solutions for the processing of feed with the use of substandard raw materials together with secondary raw materials of food production (waste of grain processing, flour-grinding, brewing industries, etc.) are presented: processing of compound feed with polysteam lactic acid sourdough based on whole-ground flour from waste processing of legumes
