Specifications Fire assay fluxes according to customers' recipe, or our own specification. Gold free and silver free type are available The famous fire assay has been around for more than 500 years, but it still is the best method for determining the quantity of gold, platinium and other precious metals, thus widely used by gochemical assay laboratories. The fire assay process works by fusing or dissolving the rock sample in a crucible using a lead glass flux. Fluxes of various types are used on various types of ores. Most flux mixes may contain the following: Litharge, Sodium bicarbonate, Silica, Borax, Flour, Florite, Etc. Gemhold does custom manufacturing of lead monoxide(litharge) with qualified manufacturer in china, producing top grades of litharge from 99.5% - 99.9%min, which are widely used in fire assay, optical glass, piezo ceramic, and other industries. For fire assay industry, gemhold can produce assay grade litharge with very low gold and silver content, say, gold less than 1.5ppb, and silver less than 0.15ppm. Gemhold can produce assay fluxes according to customers' recipe, or from our own standard. Our ability to product high quality litharge enable us to produce idea fluxes needed in the low level assay works. Our quality control system and semi-automatic manufacturing processes make our fluxes fully reliable. We can assay each batch of our flux if customers require that, and coa be be provided before despatching

Ball Clay: A member of kaolinite family, Ball Clay is renowned for its plasticity and green strength. They consists varying proportions of kaolinite, mica and quartz, with small amounts of organic matter and other minerals, and are commercially values because they increase the workability and strength of various ceramic bodies and have white or near white firing characteristics. Ball clay is processed to minimize the levels of coarse particles. This enhances better workability and higher strength. Applications : It forms a major part of many ceramic applications, including sanitary ware, tiles, table wares and to an increasing extent non-ceramic applications like functional fillers and advanced application for example technical ceramics.
Fly Ash: Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries. The Major Utilization Areas Of Fly Ash : - Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC). - Part replacement of OPC in cement concrete. - High volume Fly Ash concrete. - Roller Compacted Concrete used for dam & pavement construction. - Manufacture of ash bricks and other building products. - Construction of road embankments, structural fills, low lying area development. - As a soil amender in agriculture and wasteland development. Types of Fly Ash: - According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties. - Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product. - Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash. - Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics. Minimum Order Quantity : 1 container
Dolomite: Dolomite a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomitic limestone. Applications: - Dolomite is chosen for many construction and building product applications due to its increased hardness and density. - Asphalt and concrete applications prefer dolomite as filler for its higher strength and hardness. - Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore - Palletization and as a flux agent in steel making. - Farmers use dolomite for agricultural pH control. - The chemical industry uses the mineral dolomite in making magnesium salts including magnesia, magnesium oxide (MgO), which is used in pharmaceuticals.

Silica is mainly used as a carrier of agricultural chemicals. Finely crushed silica powder is coated with agricultural chemicals and sold on the market for agricultural use. Silica itself has no effects; it merely serves as a carrier, and so can be dispersed without affecting the farmland, which makes it advantageous as a core material. It's used as Fire-resistant product powder, Agricultural chemical carrier, Agricultural chemical carrier, Construction board
