Electro-gravimetric recovery of silver from aqueous solutions and its precursors

A simple electrolytic cell was used for electrochemical recovery of silver from aqueous solutions containing 100 mg/L Ag(I). Two different sets of electrodes were applied to find the enhanced recovery of silver. Rocks and ores samples were processed through fire assay method and acid digestion. A set of electrodes comprised of stainless steel anode and aluminum cathode gave maximum recovery (96.5%) of silver. This simple, robust, environment friendly and highly sensitive method was effectively applied to various ores and rock samples. The developed method with slight modifications can also be applied for the recovery of other metals. KEY WORDS: Boulangerite ore, Deposition, Electrolytic cell, Electrodes, Recovery, Silver Bull.

Politik Hukum Perlindungan Lahan Pertanian Dan Hak Asasi Petani Sebagai Instrumen Mewujudkan Ketahanan Pangan Berkelanjutan Di Indonesia

The legal politic of protecting Sustainable Food Agricultural Land as an effort to prevent the conversion of wet land and to protect the farmers' rights is difficult to do. However, the real effort is to establish a set of firm regulations. In some contexts, there are still some weaknesses in the policies made by the government in maintaining the land. Moreover, in its implementation, potential conflicts of interests between local governments that base their reasons on local autonomy and the central government that intends to protect food agricultural lands may happen.
