Talc powder production

Most talc deposits are mined using the open pit technique. The overburden (surface rock) covering the talc deposits is removed using giant shovels that can shift up to 1,500 tonnes of rock per hour.

Talc is extracted from the seam using shovels. At this stage, the different ore types are sorted as they are extracted from the seam.

The sorting of different talc ores according to talc content and brightness is an important stage in the production of talc. Sorting techniques include hand sorting, using state-of-the-art laser and image analysis technology or using flotation.

Talc ore is then milled to obtain the right particle size, distribution curve and top cut for specific applications. Milling techniques include using compressed air, steam and impact grinding. The median particle size can range from less then one micron to 15 microns, with top cuts from six microns to over 100 microns.

Certain grades of talc are treated, for example amine-coated talc used in fertilisers, silane-coated talcs used in the rubber industry and cationic talc for pitch control in papermaking. Talcs used for cosmetics and pharmaceutical industry are heat-treated to decontaminate them.

Talc powder is usually packaged and delivered in bags, semi-bulk bags or in bulk. There has also been an increased demand for talc in pellet form or in slurry form.

Talc extraction :

Talc is the softest rock in the world. While most people think of talc as a white substance, it can be gray, green, blue, pink and even black.

Most talc deposits are open-pit mines. The waste rock covering the talc vein is removed using giant shovels that can shift up to 1,500 tons of rock an hour.

The exposed talc is then extracted using shovels. Even at this early stage, the different ore types are sorted as they are extracted from the seam.

There are four main categories of talc deposits:

  1. Magnesium carbonate derivative ore bodies
  2. Serpentinite derivative ore bodies
  3. Siliceous or silico-aluminous rock derivative ore bodies
  4. Magnesium sedimentary deposit derivative ore bodies

Sorting and milling :

Sorting the different talc ores according to their talc content and brightness is a key phase of the production process. Techniques include hand sorting, state-of-the-art laser and image analysis technology or flotation.

To obtain just the right particle size distribution curve and top cut for a given application, the techniques used include compressed air, steam and impact grinding. Median particle sizes can range from less than 1 micron to 15 microns, and top cuts from 6 microns to over 100 microns.

Usage of talc powder

Talc is used in the manufacture of a wide range of everyday products including animal feed, automobiles, cables, sweets, ceramic tiles, chewing gum, cosmetics, fertilisers, foundry technology, olive oil processing, paint, paper, pharmaceuticals, plaster, plastics, printing inks, putties, refractories, roofing, sanitary-ware, tyres and of course body powder.

Certain grades of talc are treated, e.g. amine-coated talcs for fertilizers, silane-coated talcs for the rubber industry and cationic talcs for pitch control in papermaking. For the cosmetics and pharmaceuticals industries, talcs are heat-treated to decontaminate them.
