Flotation experiments on the mica ore were carried out in a 3 L Denver flotation cell at an air flow rate of 4.5 L/min using Cp-102a as frother. For each test a fresh batch of ore (500 g) was rod milled wet and then transferred directly to the flotation cell where the pulp level was adjusted to a set height by adding tap water.

FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Results proved that shaking table could produce a mica concentrate with grade of 74%. Also, according to the flotation tests, it seemed the best size fraction was -150+75, and after that, -100+150. Flotation in combination with attrition scrubbing produced a concentrate with 92% mica content and 70% recovery.

Also, if little or no mica is present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.
