Abstract: The gold deposits in Western Henan are mainly of quartz vein type. With the development and utilization of gold deposits, a large number of waste rocks have been formed. At present, they are mainly stacked in the waste rock yard, causing a large waste of land resources and mineral resources, and threatening the living environment of surrounding residents. The content of quartz in the waste rock of a gold mine in this area is 50.5%, and contains feldspar, mica, calcite and other minerals. The content of the main valuable element SiO₂ is 60.92%, which has utilization value. After preliminary color separation and preconcentration, a quartz product with SiO₂ content of 92.68% is obtained from the waste rock, in which the main impurity minerals are calcite, some iron bearing mica, hematite, etc. The combined process of “color separation-crushing-grinding-magnetic separation-flotation-acid leaching” is used to treat the quartz vein type gold ore waste to recover quartz. The results show that: the waste rock after color separation is subjected to two stages of magnetic separation with magnetic field strength of 1.0 T and 1.4 T（pulse frequency of 50 times/min） under the condition of grinding fineness of −0.15 mm accounting for 38.76%. The obtained non-magnetic product is then floated. The pulp pH value is adjusted to 9 with 1% NaOH as pH regulator, sodium silicate（dosage of 300 g/t） as quartz depressant, sodium oleate（dosage of 350 g/t） and sodium dodecyl sulfonate（dosage of 350 g/t） as calcite composite collector. Then, the flotation concentrate is leached with 2 mol/L hydrochloric acid solution as leaching agent, the liquid-solid ratio is controlled at 3∶1, and the leaching time is 4 h at 60 ℃. Finally, the quartz sand product with SiO₂ content of 99.91%, Al₂O₃ content of 0.056%, and Fe₂O₃ content of 0.017% could be obtained, and its quality meets the requirements of superior grade silicon raw materials for flat glass. This study provides an effective way for the mass consumption and comprehensive utilization of similar mine waste rocks, and increases the supply of quartz resources while realizing the technical increase of storage.
