context_section_description: The Lincoln family began to acquire Bagdad Mining stock in the latter part of World War II. By September 1944, Lincoln acquired 50% in the Bagdad Mine stock and had become the president of the Bagdad Copper Company. The Bagdad Mine represents one of the largest copper reserves in the United States and in the world, having estimated reserves of 873.6 million tonnes of ore grading 0.36% copper. It is located in Yavapai County, Arizona, just west of the unincorporated community of Bagdad. Lincoln established a laboratory in the mining area dedicated to the research of the oxide ores. He had a small pilot plant built to test the fluosolids roasting of the sulfide concentrates. Ernest Russell Dickie, who was familiar with the Vulture Mine, became Lincolns' associate. Dickie supervised its activities throughout the years of vast expansion and development.
