Would you plz. drop me a few lines about pH increase in thickeners. My thickener acid (acid leach liquor (PLS)) retention time is too long (about 4 days) and pH gradually increases. Should I maintain Ph by adding fresh acid every day? Otherwise Ph will increase and our valuable metals re- precipitate. Thanx.

 

Set up a model based adptive control scheme. This will ive you optimum acid addition with precise control pf pH.For details contact [email protected]
