Where can I extract the element of the element, the element of the element, the element of the element,Zinc can be extracted from zinc - containing ores. Common zinc ores include galena, sphalerite and smithsonite. The extraction process mainly includes ore dressing, roasting, calcination and electrolysis. Firstly, in the ore dressing process, impurities and non - zinc minerals in the ore are separated to obtain zinc ore. Then, the zinc ore is usually roasted to remove harmful elements such as sulfur and arsenic. After that, the roasted zinc ore is calcined by heating it to about 1,200 °C to make the zinc in it oxidized into zinc vapor, which is condensed into zinc concentrate in the furnace. Finally, the zinc concentrate is usually further refined by electrolysis. The zinc concentrate is immersed in an electrolytic cell, with a steel plate as the cathode. When the current passes through the electrolytic cell, zinc ions are ionized at the anode and then reduced to refined zinc at the cathode of the steel plate.
