Pure Lead
Pure Lead Ingot is being produced from Raw Lead Bullion / Remelted and Secondary Lead Ingots / Lead Scraps though Pyrometallurgical process. Our Refining Process, producing Pure Lead Ingots with a minimum purity level of 99.97% by weight but achieves purity level of 99.985% in most of cases.
Our Plant is having three Refining Kettle / Pots with capacity of 30 MT, 16 MT & 10 MT each. Our Automatic Ingot Casting Machine cast 10 MT per hour and ensures Dross-free & smooth top surface of each ingots and almost similar weight of each ingot separately.

Lead Alloys
Our Alloying plant is capable to produce all kind of Lead Alloys as per the customer requirement Like : Antimonial, Calcium, Selenium, Copper, Tin, Arsenic, Lead Alloy, etc. We have alloying kettle of various capacities ranging from 10-30 tones per batch. They are accompanied by high efficiency furnace oil burners equipped with preheating arrangements. Emissions control is achieved by a flexible kettle hood venting into a venturi scrubber attached to an induced draft fan along with a chimney/stack arrangement.
Lead Sub-Oxide / Grey Oxide
The Greyish color Lead oxide is also known lead sub oxide, grey oxide, battery oxide. The Grey Oxide is produced in ball mill plant & the process is an enothermic reaction. The chemical forumlae of Lead suboxide is (2PbO.Pb). The Lead suboxide is used extensively in preparation of plates in Lead Acid Batteries.
Grey Oxide produced in Ball Mill Plant, which comprises of a small Lead Melting Furnace, operating in line with a hemispherical / cylindrical ball-casting machine, which feeds the balls to the ball mill. In the ball mill, Lead is converted to Lead Sub Oxide, which is an exothermic process. In this process heat is generated and temperature of a oxide is increase to control the temperature with in the range of 115 to 135OC. The ball mill is cooled with constant flow of air and also with the water spraying system controlled through solenoid valve. The Grey Oxide is harvested through a classifier high efficiency cyclone, bag-house filtration unit and induction draft fan arrangement. It is in a grey powder form. The desired particle size and free Lead content is ensured through proper plant configuration and precise control of ID Fan suction. Our plants can produce up to 350 mesh size LSO powder.

Red Lead
Red Lead is a bright red to orange, red powder which is used in making Lead glass and red pigments; paint made with Red Lead is commonly used to protect iron and steel from rusting. Chemically, Red Lead is Lead tetra oxide, Pb3O4, a water-insoluble compound that is prepared by the oxidation of metallic Lead or of litharge (Lead monoxide). The commercial product sometimes contains litharge as an impurity.
Red Lead primer is one of the oldest and most commonly used anti-corrosion pigments applied to metal surfaces. Orange-red in color, Red Lead forms the prime coat for most of the largest bridges in the world. Red Lead is also used as primer for most of the intricate steel structures of buildings built in the 20th century. Resistant to even salt water, Red Lead was liberally applied to the hulls and decks of millions of ships. Typically, 85%Red Lead (Lead concentration = 85%) was applied to these steel surfaces. Later, Red Lead primers containing as much as 95% to 98% Lead were used.
Red Leadis virtually insoluble in water and alcohol. However, it is soluble in hydrochloric acid present in stomach, therefore it is toxic when ingested. It dissolves in hydrochloric acid, glacial acetic acid, and diluted mixture of nitric acid and hydrogen peroxide.
Red Lead is used to a certain extent in the ceramics and glass, paints and pigments and explosives industries.
Our manufacturing plant for Red Lead have a Barton plant as the first step to produce messicoat. The required input is refined Lead ingots of minimum 99.97% purity. The Barton plant output is routed to Red Lead furnace with their equipment in conjunction with a dust collection plant, conveyors, grinder and cyclone-bag-house filtration unit arrangements, culminating in a packing and storage module.

Re-Melted Lead
We produce & Import Remelted Lead Ingots / Blocks, which contains about 97-99% Lead Metal with remaining Impurity Elements (Total 2-3%) as Antimony, Tin, Arsenic, Iron, Bismuth, Copper, Silver etc.
This is commercially called as ‘Raw Lead or Lead Bullion’, which is further processed to Pure Lead (99.97 purity) and / or Specific Lead Alloys.
Remelted Lead Ingots is being produced by Smelting Operation done in Blast Furnace / Rotary Furnace. India considered as one of the biggest Importer of this product.
