Three cost estimating models developed by personnel of the Minerals Availability Field Office of the United States Bureau of Mines for use in developing an order-of-magnitude cost evaluation for the recovery of thorium from domestic deposits are described. The models can be used to calculate the cost, in 1977 dollars, for recovery of thorium contained in (1) thorite vein deposits similar to deposits at Wet Mountain, Colorado, and Lemhi Pass, Idaho, (2) fluviatile placer deposits similar to deposits found in the Piedmont Belt of North and South Carolina, and (3) massive carbonatite deposits similar to those found in the Powderhorn District of Colorado. The basic concepts of the cost models are discussed and a cost format, which can be used for applying the models to specific deposits, is presented.
