Techniques for CollectorsHow to seperate lead ore from red earth
19th Dec 2007 08:43 UTCutheinlwin
I would like to seperate lead ore ( size ranging from 2" to 12" from red earth (Terrarosa soil that weathered from limestone ) in limestone area where water problem for washing the ore. We need some machine (eg. air seperator or electric seperator) which want to operate >500 tons daily to separate lead ore from red soil. Any suitable process or advise urgently,Please.

But if your lead ore is in pieces of 2-12 inches, and the soil is presumably finer than this, is there any reason that you can't just use a sieve, agitated by an electric motor? You would probably need several such setups to get >500 tons of soil processed per day.
I am assuming that your lead ore is in fairly pure chunks, but if (for example) it consists of small crystals on a matrix of red earth or limestone, these processes might not work.

Thanks for the message. The ore is mainly cerussite forms as secondary ore in residual red soil, 2m to > 50m thick underlain by limestone with galena mineralization. Main target is to separate Pb Co3 ore from the red soil which is not very compact. Using shaking table/ seiveing is a good idea but worry about the mass production eg. 500 tons/ day.

The movement of the ore in the pipe may be by gravity (inclination of the pipe) or mechanical (helicoidal flange inside the pipe).
