Our talc powder comes from talc rich state of INDIA, Rajasthan. Talc powder is our core material and we are very confident for the quality and consistency of our material. The material that we supply can be easily customized on the basis of mesh size, calcium, iron and whiteness. (Whiteness 85-97% Extra)

Washed clay is produced by levigation process where raw china clay is mixed with water to create milk shake like slurry.This slurry is processed through De-Gritting, Soldi Liquid Separtion, Filtering And Drying Process & it becomes water washed is used in various industries lie Rubber, Paper, Ceramic, Glass, Paint, Plastic and others.

The Mineral quartz mainly comprises of silica (SiO2) which serve as a vital input for various industries. Quartz powder can be supplied on the basis of their whiteness and their end use. We differentiate our material as snow white quartz, super quartz and semi quartz on the basis of their physical appearance and whiteness. We can supply powder as well as grains of quartz as required by the customer.

The properties of talc that enable its use in a wide variety of applications are its extreme softness & smoothness, good lustre & sheen, high slip & lubricating property, low moisture content, ability to absorb oil & grease, chemical inertness, high fusion point, low electrical & heat conductivity, high dielectric strength, good retention for filler purposes, whiteness, good hiding power as pigment and high specific heat. Our Talc chips are mainly used by ceramic industries making tiles. We supply our material to domestic as well as export market. Because of its softness, smoothness and good firing properties our material has been recognized globally by leading manufacturer of tile industries.

Sodium feldspar is highly used due to the alumina, sodium content and the minerals ability to act as a flux. The alumina content of sodium feldspar is over 19%. Furthermore, sodium feldspar can be used in paints, plastics, ceramic flooring, fritz and glazes. This improves the strength, toughness, and durability of the ceramic body.Feldspar also is used as fillers and extenders in applications such as paints, plastics and rubber. Beneficial properties of feldspars include good dispensability, highchemical inertness and others.

We have various grades of sodium feldspar powder for their use in various industries. The sodium content of our material ranges from 5-11%. We have setup automated VSI plant for grinding lumps into powder and grains which has strong magnetic belt, blowers and other mechanical functioning for removing impurities like iron and mica thereby giving our clients the best quality material.

We have various grades of potassium feldspar powder for their use in various industries. The potassium content of our material ranges from 5-11%. We have setup automated VSI plant for grinding lumps into powder and grains which has strong magnetic belt, blowers and other mechanical functioning for removing impurities like iron and mica thereby giving our clients the best quality material.

Ball clay and China clay differ only in the degree of plasticity. China clay is less plastic than ball clay. Ball clay is a highly plastic variety of kaolin having high binding power, tensile strength and shrinkage. Ball clays or plastic clays are fine grained, highly plastic sedimentary clays, which fire to a light or near white colour. They are used mainly in the manufacture of ceramic white ware and are valued for their key properties of plasticity, unfired strength and their light fired colour. Ball clays exhibit highly variable compositions and consist of a mixture, primarily of kaolinite, mica and quartz, with each contributing different properties to the clay.

Calcined clay is produced when raw kaolin or more popularly known as Clay or China Clay is fired enough to reduce its crystalline water content via a process known as Calcination. The calcination process increases whiteness and hardness of the Clay, improves its electrical properties, and alters the size and shape of the kaolin particles. Calcination makes the powder whiter and more chemical inert. Calcined Kaolin is used as a functional extender in paint. Calcined kaolin has proven to be an excellent extender for titanium dioxide (white) pigment in paint.

Kaolin is commercially valued for its whiteness and fine particle size which distinguish it from other clays, such as, ball clay and fireclay. Other physical characteristics that influence commercial utility include brightness, glossiness, abrasiveness and viscosity. The whiteness, particle size, plasticity, contents of alumina, iron and titanium are some important factors which control the specifications of China clay for different end-uses. We at R.k Minerals are supplying various kind of china clay which are used in various industries for their specific needs. Our clay is mined, proccessed and supplied with latest machinery and experts in the field of mining.

Wollastonite is chemically a Calcium Meta Silicate (CaSiO3), it is a naturally occurring white & acicular (needle shaped) mineral, with mohs hardness of 4.5. In addition to Wollastonite's unique morphology, it is alkaline, inert, has low loss on ignition, low water solubility, low co-efficient of linear thermal expansion and a melting point of 15400c. It also improves tear strength, dielectric properties and retains mechanical properties at elevated temperatures.
