Maximizing recovery of water soluble proteins through USA Process of recovering copper and of

We herein provide an in depth characterization of protein recovery through acetone precipitation In 80 acetone the precipitation efficiency for six of 10 protein standards was poor ca ≤15 Poor recovery was also observed for proteome extracts including bacterial and mammalian cellsThe precipitation is preferably effected at a pH value of 15 to 20 The free hydrocyanic acid is recovered as alkali cyanide or alkaline earth cyanide and is recirculated to the leaching stage A process is described by which copper and optionally silver and gold are recovered from sulfide and oxide ores concentrates or slag which contain the metals
