摘要： Copper is recovered from an aqueous pulp of an ore containing both sulfide minerals and oxidized minerals by continuously monitoring the EMF of the pulp and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of contained sulfur per ton of ore whenever and for so long as the pump EMF is above about -30 millivolts with reference to a standard silver-silver chloride electrode, and discontinuing such addition whenever such EMF in less than about -30 millivolts. Thereafter the pulp is subjected to a froth flotation operation in the presence of a collector for copper sulfide minerals to produce a concentrate containing most of the sulfide minerals and a substantial part of the oxidized minerals of the ore.

摘要： Snap ring pliers include a first section having a first jaw portion with a first outer end and a first tip projecting outwardly from the first outer end, and a second section having a second jaw portion with a second outer end and a second tip projecting outwardly from the second outer end. The first tip opposes the second tip. A pivot pivotally couples the first section to the second section for movement of the first and second jaw portions between closed and open positions. The first and second tips are joined forming a tongue adapted to be received in a snap ring gap in the closed position of the first and second jaw portions, and the first and second tips are spaced apart and separated by a gap in the open position of the first and second jaw portions.

摘要： Snap ring pliers include pivotally attached first section and second sections having first and second respective jaw portions, a first tipped part having a first minor tip and a first major tip, and a second tipped part having a second minor tip and a second major tip. A pivot pivotally couples the first section to the second section for movement of the first and second jaw portions between closed and open positions. The first and second tipped parts are removably connectable to the respective first and second jaw portions in first orientations for forming a minor snap ring gap tongue by the first and second minor tips in the closed position of the first and second jaw portions, and for forming a comparatively larger major snap ring gap tongue by the first and second major tips in the closed position of the first and second jaw portions.
