The Counter-Balanced Laboratory Pressure Filter is designed to handle bucket samples of mill pulps. Due to the counter-balanced mechanism, it can be operated as easily and quickly as the smaller sizes. While the filter is being filled, the cover is held back by the weight of the counter-balance. During filtering, the yoke holds the filter medium tightly … Read more
Suspended solids are a common impurity in mine water. Mines rely mainly on flocculation and settling for solid removal, but this can be unreliable owing to seasonal variation in water temperature, runoff, and changes in the character of ores being mined. Filtration is often needed to provide sufficiently pure water to meet mineral processing requirements … Read more
Crushed ore is reclaimed in a 3.7 m (12′) diameter tunnel with, two variable speed slot feeders. Mill feed is conveyed to a 3.7 m x 1.2 m (12′ x 4′) 250 hp semi-autogenous (SAG) mill. Lime is screw fed onto the conveyor inside the reclaim tunnel. The SAG mill discharge enters a common sump shared … Read more
GORE-TEX membrane filter cloths for liquid filtration consist of expanded polytetrafluoroethylene (PTFE) membranes bonded to a variety of felts and other fabrics (including fabric woven of PTFE fiber). The PTFE membrane/PTFE fabric filter cloth is inert to practically all chemicals and can be used at temperatures up to 500°F (260°C) . These materials combine the … Read more
The pressure filtration of flocculated suspension was described as a compressional theology model far evaluation of filtration data. Others divided the filtration process into two stages as compact formation (stage 1) and compact consolidation (stage 2) stages. They developed a conventional engineering approach for analysis of stage 2. In this study, conventional filtration theory was … Read more
The chemicals involved in the work of this paper utilize a combination of mechanisms: charge effect neutralization and polymer bridging. There are a number of trends in the results that support this dual mechanism. The slow settling rate and insensitivity of changes in coagulant concentration are the typical effects of compounds used for charge neutralization. … Read more
As part of its mission to effect pollution abatement in mineral processing, we entered into a cooperative research project with 10 Florida phosphate mining companies. The objectives of the project were to seek means for disposing of phosphatic clay wastes and for reclaiming mined land. Phosphatic slimes represent one of the principal waste products resulting from … Read more
