Abstract

685,590. Mould materials. FREUDENBERG, H. Jan. 1, 1951 [March 13, 1950], No. 5/51. Class 83 (i). Finely-divided glauconite is used as the plasticizing means for sand to be used for moulding. Plain sand may be mixed with the glauconite to form moulding sand or glauconitecontaining sand from natural deposits may be freed from clay by washing and then passed through a grinding mill which has the effect of finely-dividing and distributing the glauconite without effecting the harder sand grains. Finely-divided glauconite for mixing with plain sand or adding to moulding sand may be obtained from natural glauconite-containing sand by grinding as above and then removing the finely-divided glauconite by washing-out, blowing-out or screening-out.
