This experimenl indicates clearly that the amount of oil adsorbed increases as thenit of mineral surface increases. This is perfectlynatural and serves as a reliable check on these experi-ments. In flotation it is therefore to be inferred that theamount of oil used should be in proportion to the size ofthe mineral particles to be floated, to the percentage offloatable mineral surface, the contents in the ore. and thent of water used in the and Adsorption.
