Background
Ores such as copper oxide, lead, zinc, cobalt and the like are important mineral resources, and the efficient utilization of the ores has important significance for guaranteeing the safety of resources and meeting the requirements of nonferrous metals. Flotation is the most economic and effective means for recovering the enriched minerals at present. Compared with corresponding sulfide minerals, the oxide minerals have large surface wettability, are relatively difficult to directly float, and need fatty acid or fatty amine medicaments with long carbon chains, but the medicaments have poor selectivity and large dosage. In industrial practice, a sulfidation flotation method is generally adopted to recover oxidized minerals, sulfidation is a key link of the process, and the effect of sulfidation directly influences flotation indexes.
The most common sulfidation method used in industrial practice is the addition of sodium sulfide solution to the pulp, also known as surface sulfidation, by the mechanism: the method is characterized in that sulfur ions in ore pulp and mineral particles are subjected to multiphase chemical reaction, metal sulfide (MeS) is generated and covered on the surface layer of oxidized minerals to form an oxidized ore/sulfide multiphase composite structure, as shown in figure 1, sulfide has strong surface hydrophobicity and stronger adsorption capacity on a collecting agent, and sulfide can activate flotation of the oxidized minerals.
In the concentration range of the flotation reagent, the amount of the sulfide product generated after vulcanization is very small, and due to the structural characteristics shown in figure 1, the travel of X rays, infrared light and the like in the sulfide product is short, and the signal generated after action is weak; the effective signals of the sulfide are difficult to collect by using analytical test means such as ordinary powder diffraction, infrared spectroscopy and the like, so that the phase, the physical and chemical properties and the like of the sulfide product cannot be effectively characterized in the past, and the research on the sulfide flotation of the oxidized minerals is slow for many years.
The sulfuration is a key link for flotation and recovery of minerals such as copper oxide, lead, zinc and the like, and the quality of the sulfuration directly affects the flotation indexes, so that effective information is obtained by extracting surface sulfuration products of heavy metal oxidized minerals such as copper, lead, zinc and the like and characterizing the physical and chemical properties of the heavy metal oxidized minerals through a modern analysis and test means, and the method has important guiding significance for industrial practice of the sulfuration and flotation of the oxidized minerals.

Example 1: the white lead ore is the lead oxide mineral with the most industrial recovery value, the yellow sulfur method is used for recovering the lead oxide ore industrially at present, and the vulcanization is an important link of the process. The reaction formula of the sodium sulfide-sulfidic galena can be represented by the formula (1):
PbCO3/PbCO3 +Na2S →PbCO3/PbS +Na2CO3 （1）
scholars at home and abroad do a great deal of research work in the field of sulfidation flotation of white lead ore, but still some unsolved problems exist: as mentioned above, due to the limitation of XRD instrument sensitivity, no diffraction signal of PbS (lead sulfide) can be detected in the range of the amount of sodium sulfide used for flotation; in order to determine the phase of the vulcanizate, researchers have typically added extremely large amounts of vulcanizing agents. But the sulfide flotation behavior of the oxidized ore is closely related to the amount of sodium sulfide, and the recovery rate of the oxidized ore increases along with the increase of the amount of sodium sulfide within a certain sodium sulfide amount range; when the amount of sodium sulfide exceeds the optimum amount, the recovery rate decreases as the amount of sodium sulfide increases. Therefore, the sulfide product phase at the optimal sodium sulfide dosage is determined, the physicochemical properties of the sulfide product phase are explored, and the method has positive significance for the flotation practice of the lead oxide ore. This example describes a method for extracting a pure mineral sulfide product of galena, and the phase of the sulfide product is characterized;
