    Pengaruh Konsentrasi Pelarut Dan Rasio Padat-Cair Pada Ekstraksi Silika Dari Fly Ash (Abu Terbang) Batu Bara
    (2015-12-12) Thamrin, Ali; Aman; Sunarno
    Using coal in industrial and power plant always increase every year. Increasing using of coal linearly with number of productrion waste of fly ash from coal. One of alternative method for using fly ash as raw material of silicate. On this research using some variable : solvent consentration (2, 2,5 and 3M) and ratio of solute – liquid (1:6, 1:8 and 1:10). From the analysis of sample with using gravimetry method acquired optimal condition on solvent consentration 3 M and ratio solute-liquid 1:10 with silicate convertion 41,3%.
