CHARACTERISTICS OF NDEBELE CLAY

CHEMICAL ANALYSIS AND PHYSICAL PROPERTIES OF KAOLIN MINED BY NDEBELE MINING COMPANY (PTY) LIMITED

The geochemical thumb print for the Ndebele Kaolin is characteristic of the plastic “fire clays” (i.e. high aluminium, low iron, low bulk density, plastic kaolinitic clays) of the Karoo Supergroup in the Bronkhorstspruit area of Gauteng/Mpumalanga. The kaolinite content could be as high as 89% depending on the mica content. Potassium is present and indicates the presence of some mica or interstratified illite-mica and/or smectite, however, in subordinate concentrations. The quartz content is lower than 8%. The high kaolinite and therefore alumina content increases the refractoriness of the body in which the clay is used. The clay is suitable for refractory applications, as a filler in the rubber industry, as a filler in the adhesives industry (eg particle board), in the fertilizer industry, crucibles, bricks, etc.

Chemical Analysis of Ndebele Kaolin
  • Silicon, as Si02   46.83%
  • Titanium, as Ti02   2.05%
  • Aluminium, as Al203   36.26%
  • Total Iron, as Fe203T   2.04%
  • Manganese, as Mn0   <0.02%
  • Magnesium, as Mg0   0.28%
  • Calcium, as Ca0   0.15%
  • Sodium, as Na20   <0.02%
  • Potassium, as K20   0.24%
  • Phosphorus, as P205   0.06%
  • Loss on Ignition   12.53%
  • H2O-   3.9%

The above kaolin/fireclay can be produced with various grades of moisture ie -1% or -8%.

We also supply NPRaw – raw (unmilled) kaolin, NPP (partly processed) with 90% passing 35# or NPC

(Classified) with 90% passing 200 micron.

The above data is typical of our normal production and is subject to normal variation, and should not be taken as a binding specification. Where a property is critical, confirmation should be obtained from Ndebele Mining Co (Pty) Ltd.
