The improvement made with kaolin processing was anticipated since the microbubble flotation column was originally designed to upgrade fine particles. The same technology may be used for coarse particle flotation as well. To test this possibility, several phosphate samples were obtained and floated using laboratory- and pilot-scale columns.
