Robert Shoemaker was formally inducted into the National Mining Hall of Fame on Sept. 24, 2016 during the 29th Annual Induction Banquet in Las Vegas.

Robert Shoemaker was one of the most operations savvy engineers of his time. With a keen eye for detail, he had an uncanny ability to spot the weak link in a design and a devotion to the practical application of appropriate theory. Shoemaker has numerous process designs to his credit but it was precious metal extraction that really distinguished him from his peers. He was a leader in the revolution in gold metallurgy in the late 1970’s, 80’s, and 90’s: the three components of which included 1) the introduction of heap and dump leaching on a large scale to treat low grade ores; 2) the widespread adoption of carbon absorption systems for metal recovery from cyanide solution; and 3) the development of methods to effectively process refractory sulfidic ores including chlorination, roasting, and pressure oxidation. Shoemaker had a huge impact not only in mineral processing, but also in mentoring young people and seeing them advance in their careers. He and his wife Jean pledged $1 million for Ph.D. grants in minerals education to the SME Foundation.
