Dear Sir

we are apioneer company in calcium carbonates manufacturing and grinding

our source of calcium carbonates is metamorphic calcium carbonate (marble)

So I am asking about how we improve the whiteness of calcium carbonates because some paints companies complain from this

Really I have a suggestion to improve the color by

* adding talc mineral powder ratio 5:1 %

Or adding limestone has greater or more whitness

but I am so worried from this

what can I do in this problem ?

Great any reply of any member and thank you

Sincerly
