| Abstract: | Ludwigits ore was used as raw material to prepare the borax containing Na2B4O7 10HaO over 97% by means of a process as follows. Melt and reduce the ore with carbon, then separate the molten iron from slag. As a result of that the molten slag containing boron oxide reacts with sodium carbonate, sodium borate slag is formed, then leach it by water at a given pressure. After filtering, concentrating and crystallizing, the borax is finally obtained. Pulverization and injection techniques are applied to the new process against molten slag. Based on the X-ray analyses made to raw material,intermediates and resultant, the fundamental reaction processes are discussed. |
