Recovery Formula:
From: | To: |
Definition: The Recovery of Solute in Leaching column is defined as the ratio of the amount of solute recovered to the amount of solute feed into the column.
Purpose: It helps chemical engineers determine the efficiency of solute extraction in continuous leaching operations.
The calculator uses the formula:
Where:
Explanation: The formula calculates what fraction of the entering solute is successfully recovered by comparing the amounts in the entering and leaving underflows.
Details: Proper recovery estimation helps optimize leaching processes, minimize solute loss, and improve process economics.
Tips: Enter the solute amounts in kg/s. The entering solute amount must be greater than zero. Recovery will be between 0 (no recovery) and 1 (complete recovery).
Q1: What does a recovery of 0.8 mean?
A: A recovery of 0.8 (or 80%) means 80% of the entering solute was successfully recovered in the process.
Q2: Can recovery be negative?
A: No, recovery ranges from 0 to 1. Negative values would indicate measurement errors.
Q3: What if more solute leaves than enters?
A: This would give a negative recovery, indicating a problem with measurements or process assumptions.
Q4: How can I improve solute recovery?
A: Increase leaching time, optimize solvent flow rates, or improve contact between solvent and solid.
Q5: Does this account for solute in the overflow?
A: This formula specifically calculates recovery based on underflow solute amounts only.
