TLDR
A froth flotation method for the recovery of copper, nickel, cobalt, oxide, silicate, sulfide, arsenide, and antimonide minerals from their ores over iron sulfides, silica and silicates was proposed in this article.Abstract:
A froth flotation method for the recovery of copper, nickel, cobalt, oxide, silicate, sulfide, arsenide, and antimonide minerals from their ores over iron sulfides, silica and silicates, as well as for the recovery of silicate minerals of lithium, sodium, potassium, and caesium over silica and feromagnesian silicates, and for the recovery of potassium halides and sulfates over sodium and magnesium halides and sulfates, and for the recovery of barium and strontium sulfates and carbonates, which comprises; subjecting the comminuted ore of aforesaid metals and minerals to froth flotation process in the presence of nitrous acid and an effective amount of a combination of ternary sulfonium nitrite and ternary stibine dinitrite, and potassium, sodium, ammonium nitrite, calcium strontium, barium, and iron dinitrite; the indicated compounds provide selectivity and recovery of aforesaid metal and mineral values.read more

Method for extracting carbonaceous matters in gold ores
Yang Hongying,Liu Qian +1 more
TL;DR: In this article, the authors proposed a method for extracting carbonaceous matters in gold ores, which consists of three steps: firstly, using hydrochloric acid to remove the carbonate minerals in the gold ore; then, using the hydro chloric acid and the hydrofluoric acid to extract silicate minerals from the gold oxide; and finally, using a heavy-liquid flotation method for separation so as to obtain the carbonaceous matter in gold oxide.
