Title: Marcy J Kramer: Innovator in Metal Recovery and Titanium Processing
Introduction
Marcy J Kramer is a distinguished inventor based in Arvada, CO (US). She has made significant contributions to the fields of metal recovery and titanium processing, holding a total of 2 patents. Her innovative approaches have paved the way for advancements in the extraction of valuable materials from low-grade ores.
Latest Patents
One of her latest patents focuses on the recovery of precious metals from refractory low-grade ores. This process involves treating low-grade refractory gold ores, which may also contain silver and other metal values, by partial roasting of concentrate to remove controlled amounts of sulfur and carbon. The ores are then subjected to oxygen pressure leaching to oxidize further amounts of sulfur and carbon, allowing for the dissolution of base metals and a portion of any silver present. The residue is subsequently cyanided to dissolve gold and remaining silver, which are then recovered.
Another notable patent by Kramer is the production of potassium hexafluotitanates using dilute hydrofluoric acid. This process recovers fluorine from dilute hydrofluoric acid solutions, such as waste scrubber solutions obtained in the treatment of phosphates. The dilute solution reacts with oxidic titanium material to solubilize the contained titanium, subsequently forming crystals of K.sub.2 TiF.sub.6 in the presence of potassium ions. These crystals are commercially useful as a grain-refining agent in the manufacture of aluminum alloys.
