F L vacuum disc filters are playing a vital role in preparing tailings slurry for a backfill application at a new copper mine in the Democratic Republic of Congo. According to Maria Paula Lucero, sales and account manager at FL, the company ...
4/4/2013· Here concentrates coat the ceramic disk segments during immersion in slurry baths and dewatering starts immediately via capillary action. Extracted filtrate passes through microporous holes in each disk before being transferred away by a small 2.2 kW vacuum pump. The dried filter cake that remains is continuously scraped off, as the disks rotate.
cleaned in several flotation steps. After sedimentation in thickeners and filtration in automatic filter presses or vacuum filters the typical copper concentrate contains 25 35 % Cu and about 8 % moisture. The moisture content of the concentrate is a compromise between transporting
These vacuum filters provide high extraction efficiency, low cake moisture, increased production, and reduced operating costs, while achieving maximum filtration area. Disc filters Slurry and mechanically agitated; best used when dewatering free settling solids to form a non binding cake, especially applicable where large filtration areas are required.
This filter is made by the Oliver United Filters in four sizes: 4, 6, 8½, and 12½ ft. in diameter with 1 to 12 disks. In operation the thickness of the cake ranges from 1/8 to ¾ in., depending on the material being filtered. As the disk slowly revolves, each sector in sequence rises from the pulp with vacuum
