Title: George Puvvada: Innovator in Metal Separation and Recovery
Introduction
George Puvvada is a notable inventor based in Markham, Canada. He has made significant contributions to the field of metal separation and recovery, holding a total of four patents. His innovative methods focus on efficiently extracting valuable metals from various feed stocks.
Latest Patents
One of George Puvvada's latest patents is a process for separating iron from other metals in iron-containing feed stocks. This invention outlines a method for separating metals such as zinc, lead, and cadmium from iron in secondary feed stocks like EAF Dust, BOF Sludge, mill scale, iron fines, and tire dust. The process involves reduction roasting the feed stocks at a temperature that volatilizes the zinc and other metals into metal fumes while keeping the iron intact. The metal fumes are then collected as a metal dust, which is subsequently leached with a liquid to form a leach liquor and a leach residue. The leach liquor undergoes purification through zinc dust cementation, leading to a purified liquor and a zinc dust cement residue, followed by a zinc recovery step.
Another significant patent by Puvvada is for the recovery of titanium in mixed chloride media. This process involves leaching a value metal from titanium-bearing ore material using a lixiviant that includes chloride and hydrochloric acid. The leaching occurs at atmospheric pressure, ensuring that titanium remains in solution while maintaining a temperature below 85°C and a hydrochloric acid concentration of less than 20%. The preferred chloride used in this process is magnesium chloride, which may also contain an oxidant such as sodium chlorate or chlorine.
