Latest Patents

Aimo E. Järvinen holds two patents that showcase his expertise in hydrometallurgical methods. The first patent involves a hydrometallurgic method for processing raw materials containing zinc. This invention relates to a unique technique for the recovery of various valuable materials during the hydrometallurgical production of zinc. The method is particularly effective for feeding diverse types of raw materials into different stages of the production process under atmospheric conditions. As a result, valuable metals, including lead, silver, and gold, can be successfully extracted.

The second patent focuses on the flotation recovery of lead, silver, and gold as sulfides from the iron-bearing residue of an electrolytic zinc process. This process is critical in separating these valuable metals from the residue by froth-flotation. By employing a sulfidic collector agent, Järvinen's method allows for the selective sulfidization of iron-bearing residues, enabling nearly quantitative conversion of lead, silver, and potentially gold into sulfides before separation.
