For the separation of kaolin in the quartz, feldspar, mica, iron minerals, titanium minerals such as clay minerals and organic matter, produce kaolin products to meet the needs of various industrial sectors, in addition to the re-election, flotation, magnetic separation of kaolin purified impurity, and sometimes chemical bleaching, ultra-fine flakes, calcined, surface modification and other deep-processing method for processing of kaolin.

Hydraulic classification spiral classifier (separation +1 mm coarse sand), sedimentation tanks classification (separation the +0.053 mm of fine sand), of hydrocyclone classification (separation-0.053mm fine sand), the centrifugal classifier or small diameter hydraulic cyclone classification (for ultra-fine-grained grading 0.002 ~ 0.010mm).

By adding flocculants, the selective separation of fine-grained quartz, pyrite, alunite and other impurities, producing blade coating grade kaolin. Top flocculant, sodium hexametaphosphate, polyacrylic acid such as ammonium, sodium silicate.

In a stripping machine by stirring fine media ball grinding stripping role, kaolin aggregate particles are separated into a sheet crystals, production size of less than 2m content of more than 90% of the blade coating grade kaolin.

In 800 to 1 000 C calcined kaolin water loss, phase transformation, while some impurities to volatile, improve kaolin whiteness and insulation, production of cable and rubber plastic filler. Calcined kaolin required processing method of coal measure (hard).

Dry mined ore passes through the crusher crushing to 25mm, giving into the cage crusher, the particle size is reduced to about 6mm. The moisture of kaolin to about 10% from about 20% of the recovery time of the hot air blown into the cage crusher. The broken ore then by further pulverized with a centrifugal separator and cyclone blowing Raymond. This process can remove most of gravel applicable to the processing of those raw ore whiteness, low content of sand, the particle size distribution suitable ore. The dry processing low production costs, usually cheap fillers for rubber, plastic, paper and other industrial products.

Kaolin is an important and widely used industrial mineral which is refined from Kaolinite. It is a naturally occurring mineral of the clay family and may contain a number of impurities such as quartz, feldspar, tourmaline, ilmenite, zircon, etc, which were derived from the parent rock.

The bulk of the Kaolinitic clay deposits in the country are either sedimentary or residual in origin and are usually associated with granitic rocks. Occurrences of kaolin have been recorded in different parts of the country and specific abundant deposits have been identified in parts of Enugu, Anambra, Kaduna,Katsina, Plateau, Ondo, Ogun, Oyo, Bauchi, Sokoto, and Borno States.

Kaolin has many industrial applications in paper, ceramic, rubber, and plastics industries. Paper industry is the main consumer where Kaolin is used as filler in the sheet and coating on the surface of the sheet and new applications are still being discovered. It is used,among others, in paper, paint, rubber, plastics and ceramics industries.

Kaolin beneficiation plant depends on the nature of the crude ore and product end use. There are two kinds of application process in industrial production line: dry process and wet process. Usually the hard kaolin choose dry beneficiation plant and soft kaolin adopt wet beneficiation plant.

In the kaolin beneficiation process, crushing is the important procedure. Usually kaolin crushing process includes primary crushing and secondary crushing. Cone crusher is used as kaolin crusher in the kaolin primary crushing process. It can crush kaolin into small pieces with the size less than 25mm. Kaolin Cone crusher is used in kaolin secondary crushing process. Crushed kaolin after cone crusher is less than 6.35mm.

Nigerian Kaolin is known to have purity as high as 90% and an estimated that the annual national demand for kaolin is over 350,000 tones with local production meeting about 80% of the demand and the remaining sourced through importation.

Egypt has large reserves of kaolin in many localities in Sinai, Red Sea coast and Kalabsha near Aswan. These kaolins can satisfy the local demand for filler, paper and ceramic industries 10 times for at least 50 years, in comparison to the current demand. However, the Egyptian kaolin is hard and massive. It is also low grade so that it needs beneficiation to be suitable for paper and ceramic industries, which import their needs at the present time. Beneficiation of the Egyptian kaolin from different localities indicated their technical viability for ceramic production and as paper filler. In the meantime, the Egyptian government has created a new healthy climate to encourage investment in Egypt. For example, the government provided many facilities to investors in the new cities, increased the period of free taxes to 1020 years (depending on the project site) and reduced the interest of borrowing money from banks. All these facilities, among others, will have a positive impact on the economic viability of projects. This paper evaluates the situation of Egyptian kaolins, their methods of beneficiation and the domestic market. A summary for the economic pre-feasibility study was presented. The new laws of investment make such economic pre-feasibility more profitable in terms of return on investment (ROI) and pay back period (PBP).
