5 Easy Ways to Calculate the Concentration of a Solution

3. Divide the mass of the solute by the total mass of the solution. Set up your equation so the concentration C = mass of the solute/total mass of the solution. Plug in your values and solve the equation to find the concentration of your solution. In our example, C = (10 g)/ (1,210 g) = 0.00826.

Hydrometallurgical Processing of Low-Grade Sulfide Ore …

In cases of technogenic waste processing, the standard ore grade can be even lower. This can be explained by the fact that ore mining costs have been already spent, and transport expenses are allocated to the remediation budget [15]. The Russian Federation has all necessary conditions for a wide use of the heap leaching method for metal recovery.
