This nomograph provides a fast, convenient method for estimating production at an in situ uranium leaching operation. It has been designed to permit quick calculation of the recovery rate of uranium oxide for various mill throughput rates and pregnant solution strengths or vice versa. Each of the variables is expressed in the units of measure commonly used in the uranium industry. Using known or estimated values for any two of the variables, the third value can be read from the graph with the aid of a straightedge. The nomograph assumes 365 days per year of operation and 100 pct recovery in the mill's ion exchange system.
