COST ESTIMATE FOR PRODUCTION OF THORIUM TETRACHLORIDE AND THORIUM METAL BY THE METALLEX PROCESS

Technical Report ·
OSTI ID:4308733

The cost of producing thorium metal from thorium nitrate is estimated as 81 per pound by the PDA (propylene diamine) flowsheet and .96 per pound by the Dry Salt flowsheet. The initial plant investment for the PDA plant is higher ( 018,725) than that for the Dry Salt plant ( 235,971), but the annual operating cost, not including depreciation, is higher for the Dry Salt plant operating costs for each plant, including 20% annual depreciation, are 792,224 for the PDA plant and tons of thorium metal sinter per day (330 days' operation per year).
