When incubated with the lowest clinical value of methylcobalamin 200pg/ml (Figure 6(c)) the cells are elongated rather than cobblestone; they have a reduced cytoplasm and a rougher cell surface and they appear to have lost their ability to form a monolayer in comparison to the control Caco-2 cells (Figure 6(a)).
Finely ground raw ores are entrained to the stirred vessel, where the ores are sufficiently mixed with the reagent, then fed into a rougher cell. With the effect of reagents, valuable minerals are made hydrophobic and the others hydrophilic.
Some 10,480 [m.sup.3]/h of cyclone overflow reports to the flotation circuit which comprises four rows of nine 128 [m.sup.3] capacity rougher cells and two rows of six 128 [m.sup.3] cleaner scavenger cells.
These 50 [m.sup.3] units are operating as rougher cells.
This is conducted in closed circuit with the cyclone overflow reporting back to the rougher cells.
Cyclone overflow at 75% passing 76 microns and at 30% solids flows to two parallel banks of flotation cells each consisting of two 28.3 [m.sup.3] pre-rougher cells, four 8.5 [m.sup.3] rougher cells and three 8.5 [m.sup.3] second cleaners.
