Why are black and white barite powder

Why are black and white barite powder

Answer:

It is important to note that the barite sample quality standards you need, BaSO4 amount, and allow the impurity type and content, whether because of low prices caused by low grade goods.Because barite is white, even if there are impurities in the production of two colors mixed together, barite powder general BaSO4 content above 93%, the appearance should be gray and white, white and yellow.Hope to be of help to you.
Barite may not be black, that is to say, the black is certainly not barite, as very few black particles in white powder can be, but never make the whole color black. As for what the black is, the content is too rich, only in the sample origin can find the answer.
The chemical composition of barite barium sulfate (BaSO4), is a white mineral, the higher grade barite is white, there is no black barite, it is contaminated by impurities, color.
