The uranium mill of the Compagnie Miniere Dong-Trieu: Project preparation and implementation

The uranium ore processing plant of Compagnie Miniere Dong-Trieu (100% subsidiary of Total Compagnie Miniere (TCM)) began production in June 1979 with an annual output of 200 t uranium. The output was gradually increased to 400 t uranium in the second half of 1982 and then to 500 t in 1985, of which 70 t came from the elution of resins loaded at another mining center of TCM (processing by vat leaching). Following the description of the processing plant and the vat leaching operation, the paper presents the different stages of the development and implementation of the project from the time of the decision to create a processing plant to startup; the various stages of recruitment and training of staff which contributed to the speedy startup of the plant so that it reached the nominal production in the third month of operation; and finally the costs of development and implementation of the project.
