Crystals of serandite, natrolite, analcime, and aegirine from Mont Saint-Hilaire, Quebec, Canada. In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. [1] [2] The results indicated that appropriate galena surface oxidation and pulp oxidation environment are the prerequisites for HA adsorption on galena. Adsorbing HA on fresh galena surfaces is difficult. HA was chemically adsorbed onto lead sulfate, and the chemical equation is: (31) nPbSO 4 + 2HA n− → Pb n (HA) 2 + nSO 4 2−
