so many thanks for the anwser, but specifically I am looking, for example if the presence of certain minerals (clays, sulfates or other types) increases the consumption or the dosages of lime (grames per ton) to reach the same desired pH, and that the only thing that change is the feed mineralogy.

Dear Eduardo,

Sorry,I do not understand your question.

do you want to remove lime from the solution because it disturbs your process or you want to increase it in your solution? Or is lime used to neutralize acidic pH?

lime is CaCo3

CaCO3 in solution will keep Ph fixed to around 6 and establish a buffer soltion. That means that the pH will only change after complete reaction of CaCO3 to form Carbonate precipitates.

But if you want to precipitate the lime the better is to increase temperature because it forces it to precipitate, or cool the solution if you want to make it more soluble.

tell me more details of what you do and the reactions you have.

hi, and sorry for the missunderstanding, maybe my questions are wrong, i'm currently working in a model to predict lime consumption in flotation of copper ores, as function of mineralogy of the feed, in flotaiton of copper ores, lime is used to change the pH of the slurry to float(Normally i'ts needed a 10-10.5 pH to have good recoveries) and also to depress pyrite, that's why I need to know if the presence of some minerals could increase or decrese my consumption.
