Development of environmentally attractive leachants. Volume 4. A minitest of an in situ uranium leach solution. Open File report, 5 June 1978-31 July 1984

A minitest of the new potassium chloride-potassium carbonate two-stage in situ uranium leach process was carried out at the Intercontinental Energy Corp. Zamzow project site in south Texas. Substantial quantities of high-concentration uranium were produced, indicating the viability of the leach solution. The test results yield information regarding the reservoir dispersivity, the average cation-exchange capacity of the formation, and the distribution coefficients describing cation-exchange reactions. The test also indicates permeability anisotropy and the existence of disturbed flow fields
