In particular, the present invention involves flotation processing of goldbearing sulfide ores in a manner that reduces problems associated with conventional flotation to produce an ore concentrate. The present invention also involves the flotation processing in bination with oxidative treating, such as pressure oxidation, and use of byproduct gas from an oxygen plant used to supply oxygen gas for the oxidative treating. Significant amounts of gold are found in sulfide ores, in which the gold is associated with sulfide mineralogy. The gold is difficult to recover from such sulfide ores, because the gold is typically bound in sulfide mineral grains in a manner that renders the ore refractory to many traditional gold recovery techniques, such as direct cyanidation of the ore. Therefore, sulfide ores are monly treated to chemically alter the sulfide mineral to permit dissolution of the gold during subsequent gold recovery operations. One technique for treating a goldbearing sulfide ore in preparation for gold recovery is to subject the ore to an oxidative treatment to oxidize sulfide sulfur in the sulfide minerals, thereby rendering the gold more susceptible to recovery. One method for oxidatively treating a sulfide ore is pressure oxidation, in which a slurry of the ore is subjected to oxygen gas in an autoclave at elevated temperature and pressure to depose the sulfide mineral, freeing the gold for subsequent recovery. Other oxidative treating methods include roasting and biooxidation of the ore in the presence of air or oxygen gas. Treating whole ores by pressure oxidation or by oxidative roasting is expensive. Part of the expense is due to energy consumed in heating goldbarren gangue material in the whole ore, and especially the energy required to heat water in which the gangue material is slurried in the case of pressure oxidation. Also, process equipment for treating a whole ore must be sized to acmodate the throughout of gangue material, in addition to the throughput of the goldbearing sulfide minerals, thereby significantly adding to the cost of process equipment. Moreover, side reactions may occur involving gangue material which can detrimentally affect the oxidative treating or can produce hazardous materials which require special handling. One way to reduce the high energy and process equipment costs associated with oxidative treating of a whole ore, as well as the potential for problems associated with side reactions, would be to remove gangue material from the ore prior to the oxidative treatment. For example, one method that has been used to remove gangue material from goldbearing sulfide ores is flotation. In flotation, air is bubbled through a slurry of ore particles which have been treated with reagents and the particles of the ore which are less hydrophilic tend to attach to and rise with the air bubbles, thereby permitting separation of the ore into two fractions. Flotation has been used to prepare concentrates of goldbearing sulfide minerals which are rich in the sulfide minerals and relatively free of gangue material. One problem with flotation of many goldbearing sulfide ores, however, is that a significant amount of the goldbearing sulfide mineral often reports to the wrong flotation fraction, representing a significant loss
