Our Products
These are without definite form and are only given shape upon application. These types are better known as Monolithic Refractories. The common examples are plastic masses, Ramming masses, castables, gunning masses, fettling mix, mortars etc.
Special Quality Basic Monolithic : These are products with MgO content 50 – 94% and suitable for high temperature application as Slide Gate Nozzle Filling materials, LD Tap hole mix.
Landmark International, in order to provide end to end solutions (refractory, industrial minerals and industrial chemicals) to our esteemed clients, also deals into the below mentioned Industrial chemicals
Most of the products we use everyday are made with Feldspar, the most abundant group of minerals in the earth’s crust. Feldspar have both alkali and alumina content which makes them particularly valuable in industrial processes. Feldspar plays an important role as fluxing agent in ceramics and glass production, and are also used as functional fillers in the paint, plastic, rubber and adhesive industries.
We provide Feldspar (lumps, chips, sand, flour), nepheline syenite (sand, flour) which are widely used in glass, ceramics, paints and polymers.
Silica ( the name given to a group of minerals composed of silicon and oxygen) exists in many different forms. At Landmark International we produce the crystalline of silica and quartz as both sands and flours. Silica is hard, chemically inert and has a high melting point, making it a valuable mineral in a range of applications. We supply Wet sands, dry sand, silica flour, frac sand, filtration sand, high purity quartz, spherical silica which are mainly used in Glass, ceramics, foundry, paint and polymers, water filtration, oil & gas.
Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH) and diaspore α-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineralkaolinite and small amounts of anatase TiO2.
Bauxite is aluminium-rich ore that is used for aluminium production (the metallurgical bauxites) and for production of refractory materials, chemicals or cements (the non-metallurgical bauxites). Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage, namely :
Limestone is a sedimentary rock composed almost exclusively of calcium carbonate (CaCO3). When limestone contains a certain proportion of magnesium, it is called Dolomite or Dolomite limestone (CaMg(CO3)2).
