Title: Innovations by Valdis R Daiga in Metal Recovery Processes
Introduction
Valdis R Daiga is an accomplished inventor based in Toledo, OH (US), known for his significant contributions to the field of metal recovery. With a total of 6 patents, Daiga has developed innovative processes that enhance the efficiency of recovering iron from various materials, particularly steel mill waste.
Latest Patents
One of Daiga's latest patents is a process for treating metal oxide fines. This innovative method focuses on recovering iron from iron-bearing materials, including steel mill waste and iron-bearing ores. The process involves providing a mixture of iron-bearing materials containing iron oxides and carbonaceous material. An organic binder is blended with the mixture, which is then agglomerated to form green compacts. These compacts are loaded into a preheated rotary hearth furnace, where they are heated at high temperatures to reduce the compacts and eliminate undesirable oxides. The metallized iron compacts can then be cooled or transported hot to a steel-making operation.
Another notable patent by Daiga is the treatment of steel mill waste metal oxides. This process aims to recover iron values while separating zinc oxides and other contaminants from steel mill waste, such as blast furnace dust and mill scale. The method achieves iron metallization levels of up to 95% or more and removes zinc oxide in excess of 99%. The process includes blending the oxides with coke breeze, briquetting the blend, and firing the briquettes in a rotary hearth furnace to metallize the iron and evolve zinc and other oxide contaminants.
