This document is a compiled technical digest of U.S. patents relating to sulfuric acid leaching and associated hydrometallurgical extraction processes for various metal ores. It summarizes patented methods for recovering metals such as zinc, copper, nickel, silver, vanadium, antimony, arsenic, magnesium, iron, and uranium from silicate, sulfide, oxide, laterite, matte, dump, and refractory ores. Each entry briefly describes the process conditions (e.g., sulfuric acid concentration, temperature, pressure, residence time, and flow configuration), the main unit operations (heap leaching, pressure leaching, autoclaves, counterflow columns, milling/reactor systems), and the subsequent separation/recovery steps such as filtration, solvent extraction, crystallization, and electrolysis. The document also notes inventors, assignees, filing and priority data, and page references, indicating its role as a reference index rather than a single experimental study.
