ABSTRACT |
Before benefication of Okchun feldspar, all kinds of Fe-compounds and mafic minerals which were included in feldspar were studied. Also to produce 30/140mesh products as glass materials, optimum grinding condition and degree of liberation were studied. Fe-compounds were Biotite and Limonite, and these were existed along the cleavage. Optimum grinding time was 2min. and at this time weight percent of 30/140mesh products was 72.7% and degree of liberation at this particle size was 91.5%. |
