Ceramic industry. We offer a wide range of soda, calcium-magnesium, and sodium-potassium feldspars. Raw materials are obtained from both environmental restoration works on abandoned sites formerly exploited by third-parties and from recently identified feldspar deposits. After extraction, raw materials generally undergo different and specific treatments to increase their purity and reduce their Fe2O3 content. Finished products are available with different grain sizes to meet all different industrial requirements.
