Analysis and Testing of Lubricating Oils In Mine and Mill Production Equipment

Abstract The paper outlines: methods used for the determination of wear metals in motor and transmission oils; contaminants in motor, transmission and crusher lubricating oils; and viscosity determinations. Case histories and costs are presented to illustrate the value of an oil analysis program.
Keywords: Testing, Lubrication, Oils, Equipment, Motor oils, Transmission oils, Wear metals, Bell Copper, Preventive maintenance.

Summary: This paper describes the research that has been conducted in an effort to understand the nature and causes of sulphide fires in the Sullivan Mine. Results of the investigation have led to several theories of the origin of the fires, the nature of the chemistry and a method for assessing the fire potential. Recommendations and the implications for the mining operation are also discussed.

Summary: This paper deals with the practical problems associated with blasting a heated pillar remnant. This pillar remnant was the final stage in the blasting of a multi-stage pillar blast. Production from, the previous stages had produced burning sulphide ore, resulting in high rock temperatures in the final unblasted stage. This is an account of how, under difficult conditions, the pillar remnant was blasted.

Summary: This paper describes the concentration processes of the Sullivan Concentrator, including crushing, transportation, sink-float, grinding, flotation and dewatering. Handling of hot muck has had a deleterious effect on most of the processes, resulting in significant operating problems and poorer metallurgy. These problems are described in detail.

Summary: The burning sulphide ores in the Sullivan Mine generate sulphur dioxide gases. This paper is concerned with a description of the environmental impact of SO2 on air quality in the mine and on the surface in the vicinity of the mine. As a result of surface caving, S02 has been able to vent to surface and winds have carried it into one residential area of Kimberley. Monitoring practices are described.

Summary: Zinc production by Cominco Ltd. began in Trail in 1916 at a rate of 55 metric tonnes per day (t/d) and was increased in several increments until now electrowinning capacity approaches 750 t/d. The last increment, a 40-t/d high-productivity electrowinning plant, was commissioned in 1974- In this paper, the design and operating experience with both the existing electrowinning plant and the new high-productivity plant are described.

Summary: At the Sullivan Mine, recent experience with sulphide fires, locally referred to as "hot muck", has necessitated extensive modifications to pillar mining design and operating procedures. Potentially hot pillars are now being designed and mined to prevent fires. Unusual safety hazards and difficulties are encountered in working with, and adjacent to, existing pillar fires. Operating procedures developed for these conditions have proved successful for safe and continuing production. These...

Summary: The Falconbridge Matte Leach Process yields high-purity nickel chloride by selectively dissolving nickel from copper-nickel converter matte with hydrochloric acid, purifying the solution by solvent extraction and crystallizing NiCl^4H2O by further acidifying the purified leach liquor. In the Kristiansand Matte Leach Plant, a granular oxide is produced by high-temperature hydrolysis of the nickel chloride for subsequent reduction to a high-purity granular metal product, designated NICKEL 98....

Summary: Image analysis studies were performed on mill products from pilot-plant and laboratory tests that had been conducted to determine the effect of grinding media on the selective flotation of two zinc-lead-copper ores. It was found that, when the ores had been ground to the same degree of fineness with flint pebbles, ceramic pebbles or ore fragments (autogenous grinding) as with steel balls, there generally was increased sphalerite, chalcopyrite and galena liberation in the flotation feeds,...

Summary: This paper outlines the regional geology and history of the area, and summarizes the stratigraphy, structure and geology of the Brunswick No. 12 mine area.
The Brunswick No. 12 deposit is a stratisform massive sulfide body. It occurs in rocks of the Tetagouche Group, which is believed to range in age from Lower to Middle Ordovician. The stratigraphic sequence, including the stratiform orebody, in ascending order consists of older metasedimentary rocks, augen schist, metasediments, augen...

Summary: Since the 1940's, the bulk of the ore production from the Sullivan Mine has come from pillars. These pillars, located from 100 to 2000 feet below surface, have been subjected to considerable ground pressure. Mining techniques were adopted to minimize the problems of deteriorating ground conditions. These techniques included an orderly sequential blasting of pillars along a retreat front, stage blasting of tall pillars in horizontal slices and utilization of broken pillars as "buffers". The...

Summary: The Hat Creek coal deposits occur within folded and faulted Tertiary (Eocene) strata of the Coldwater Group, which comprises weakly lithified shales, siltstone and conglomerates underlying the floor and lower flanks of the valley of Upper Hat Creek. This upland valley, 16 miles in length and 2-4 miles in width, is located within the eastern foothills of the Coast, Mountains, 120 miles northeast of Vancouver, approximately midway between the towns of Lillooet and Ashcroft in the Interior Dry...
