On some surface deposits there is no overburden, and on others, the bauxite may be covered by up to 20 metres of rock and clay. On average, overburden thickness is around 2 metres. The bauxite layer beneath the overburden is broken up using methods such .
There are so many disadvantages of clay bricks. First of all environment is highly polluted when the clay bricks is made becasue it is produced by soil therfore a large amount of soil is needed for bricks making and then the soil is burn into fire then huge polluted smoke is generated from the brick making factory.

clay is a high alumina fire clay composed of mixed kaoliniteillite clay minerals. for most uses, it is used in its natural colors largely light to dark reddish browns.
This paper reports on the determination of the effect of Additives on the thermal Conductivity of clay. Clay sample was collected from a deposit. The clay sample was cleaned, soaked, dried, crushed and sieved. Various percentages of ashes and sawdust were added. The mixtures were used to form discs of diameter each.
of excellent ceramic clay in Hawaii. This clay was first found in 1935, in small deposits in restricted areas near the crest of Koolau Range of eastern Oahu. A considerable amount of highgrade pottery has been made of clay from this area by members of the Hawaiian Potters' Guild during the past three years. It has been supposed that clay would be

Kenya, and perhaps on Kilimanjaro, Nilsson (1935: 12) found a lower series possibly belonging to Kanjeran times. In the Kenya rift valley, Gamblian lake deposits yield Stillbay and Kenya Capsian industries. Varved clay of late Gamblian times was dated by De Geer (1934:91) to the beginning of the Gotiglacial subepoch by "teleconnec
The workhorse of the claybased refractories are the socalled fireclay materials. These are made from clays containing the aluminosilicate mineral kaolinite (Al2[Si2O5][OH]4) plus impurities such as alkalis and iron oxides. The alumina content ranges from 25 to 45 percent.
