明矾石是钾肥工业和铝氧冶炼工业的重要原料之一。它是由二氧化硫和水氧作用于含铝钾矿物变化而成。天然的明矾石分子中的钾或多或少被钠所取代,分子式应为(Na_2O,K_2O)·3A_2lO_3·4SO_3·6H_2O,当钠钾比值大于1时称钠明矾石。我国明矾石的主要伴生矿物有石英、高岭石、绢云母,白云母、长石及黄铁矿、赤铁矿、水铝石等。由于明矾石常与许多矿
Alunite is one of the important raw materials for the potash fertilizer industry and the alumina smelting industry. It is made of sulfur dioxide and water oxygen changes in aluminum-containing potassium minerals. The potassium in natural alunite molecules is more or less substituted by sodium, the formula should be (Na_2O, K_2O) · 3A_2lO_3 · 4SO_3 · 6H_2O, when the ratio of sodium to potassium is greater than 1, we call sodium alunite. Alunite main associated minerals in our country are quartz, kaolinite, sericite, muscovite, feldspar and pyrite, hematite, diaspore and so on. As alunite often with many mines
