The processing of mining products in indonesia has not been utilized optimally. One them is manganese ore. Way kanan one indonesia's potential ore sites. leaching study used a -200 mesh way that was reacted with sulfuric acid at concentrations 0.1 M, 0.5 and 1 as well corncob reductant. To separate the dissolved iron process, sulfate solution purified sodium hydroxide then filtered to have free...

A ceramic membrane modified with corncob activated carbon (CMCC) has been successfully prepared and used to reduce the concentration of remazol red in batik wastewater. This research aims study effect (CC) on porosity its ability dye The variation % CC mass clay was 0%, 5%, 10%, 15%, 20%, 25%. Characterization includes ash content characterization CMCC test, morphological analysis, elemental di...
