1. What is Original Weight of Solute Calculator?

Definition: This calculator determines the original weight of solute in solid before washing based on the remaining solute weight, solvent ratio (β), and number of washings.

Purpose: It helps chemical engineers and process technicians estimate initial solute content in batch leaching operations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S_{Solute} \) — Original weight of solute in solid (kg)
• \( S_{N(Wash)} \) — Weight of solute remaining after washing (kg)
• \( \beta \) — Solvent decanted per solvent remaining in solid
• \( N_{Washing} \) — Number of washings in batch leaching

Explanation: The formula calculates how much solute was originally present based on how much remains after multiple washing stages.

3. Importance of Solute Weight Calculation

Details: Accurate calculation helps in process design, efficiency evaluation, and optimization of leaching operations.

4. Using the Calculator

Tips: Enter the remaining solute weight after washing, the β ratio (solvent decanted/solvent remaining), and the number of washings performed.

5. Frequently Asked Questions (FAQ)

Q1: What is β (beta) in this calculation?
A: β represents the ratio of solvent decanted to solvent remaining in the solid after each washing stage.

Q2: How do I determine the remaining solute weight?
A: This is typically measured experimentally after the washing process is complete.

Q3: Does this formula work for continuous leaching?
A: No, this formula is specifically for batch leaching operations with discrete washing stages.

Q4: What if my β value changes between washings?
A: This calculator assumes constant β for all washings. For variable β, more complex calculations are needed.

Q5: Can I use this for any solute-solvent combination?
A: Yes, as long as the washing process follows the assumptions of the formula (complete mixing, constant β, etc.).
