	Hi there, i would like to ask you about how to manufacture bleaching earth from bentonite? After i've read many resources that tell me the process can undergo in two ways, heat treatment or acid treatment. That's as far as i know. How about operational condition? what the best way to activate bentonite, the heat ways or the acid ways? How far the technology of this process go in this future? cause i just read some resorces from 50-60's. Can you inform me the latest progress of this process? Please help me through this. I just don't know where i must learn this kind of process. If you have any suggestion in title of paper, handbook, or some related articles. I'm happy to know, thanks in advance.

	You mean Leaching, not Bleaching. __________________ "Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone." - Ayn Rand

	I mean bleaching. Bleaching earth will used to remove colour body impurities like carotene and others like phospolipid from vegetables oil.

	What kind of control over the starting material do you have? Are you constrained to using local soil? If so, and it is high in organic material, it is going to be quite an involved (and therefore expensive) process. If you know the starting material, you must have testing done before you can conduct a proper engineering evaluation. Have you done this? If so, post the results! __________________ "Reason is not automatic. Those who deny it cannot be conquered by it. Do not count on them. Leave them alone." - Ayn Rand

	What's "bleaching Earth" anyway? __________________ The doctor said "just one post or reply aday in CR4, take it or leave it". I said, "what does that mean?"
