Solute Underflow Formula:
From: | To: |
Definition: This calculator determines the amount of solute leaving in the underflow of a continuous leaching operation based on the entering solute amount and recovery rate.
Purpose: It helps chemical engineers and process designers evaluate solute distribution in leaching processes.
The calculator uses the formula:
Where:
Explanation: The formula calculates the solute that remains in the underflow stream after accounting for the recovered solute.
Details: Accurate calculation helps optimize leaching processes, design separation systems, and evaluate process efficiency.
Tips: Enter the solute amount in entering underflow (kg/s) and recovery rate (0-1, default 0.8). All values must be positive with recovery between 0 and 1.
Q1: What is solute underflow in leaching?
A: It's the stream containing the carrier solid and unextracted solute that leaves the bottom of the leaching column.
Q2: How is recovery rate determined?
A: Recovery is typically determined experimentally or from process data as the ratio of solute recovered to solute fed.
Q3: What units should be used?
A: The calculator uses kg/s for solute flow rates, but any consistent mass/time units can be used.
Q4: Can recovery be greater than 1?
A: No, recovery is a fraction between 0 (0%) and 1 (100%).
Q5: What if all solute is recovered?
A: With 100% recovery (1.0), the underflow leaving would contain zero solute.
