Crown Management Jakarta Capital Discussion: First of all I haven’t heard of frac sand before and I want to have a better understanding. Can anyone tell me what this is and what it’s for? And if it is that dangerous, why continue mining it then? I am sure that whatever it is used for, there are better and less harmful alternatives.
