On-site recycling of bypass dust within the industrial process can be done as a raw material to produce clinker. The wet process was found to be efficient and economic where 87% of the alkaline salts were removed by this method. On the other hand, the dry process requires treating the dust to remove the salts before mixing with the raw materials.Web
