The company was also expending 6 million to develop a new mine 11 and what became the No. 7 concentrating mill. 6. At the new concentrating mill, iron ore was fed by a conveyor belt to highintensity wet magnetic separators. 4 The metal was then passed over several screens to separate the rock into different sizes.
The Bokum Mill construction began with the expectation that uranium ore from nearby mines would be milled. However, as the price of uranium declined in the early 1980s, mining ceased and the mill was never put into operation. Construction of the mine and mill was never completed, and neither facility was ever operated.
