Essential Mineral for Survival– Copper regulates the Thyroid, makes our bones strong, aids in the formation of new cells, helps with iron absorption, and is the primary element responsible for producing. Why Copper is Used in Ayurveda
In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
