The chewing gum business is, however, just one example of talc's use in the food sector. For the past 20 years or so, olive oil processors in Spain have been taking advantage of talc's unique characteristics to help them boost the amount of oil they extract from crushed olives.
Found abundantly on the planet, talc is renowned for its unique characteristics such as softness, water repellency, and chemical inertness. Talc, in its pure form, is a hydrous magnesium silicate, denoted chemically as Mg 3 Si 4 O 10 (OH) 2. Due to its natural occurrence in metamorphic rocks, the extraction of talc often involves mining.

The maximum extraction of MgO in the concentrate was seen for samples with very fine particles because of the high selectivity toward freely-moving fine particles. The gravity concentration method gave a concentrate that contained 43.85% MgO and constituted 39.8% of the extractable MgO. The tailings contained 61.41% talc for 89% extraction.
