LEAD OXIDE MANUFACTURING

There are three oxides of Lead with commercial applications:

  • Lead Sub-Oxide (2PbO.Pb), also known as Grey/ Lead Oxide
  • Litharge (PbO)
  • Red Lead Oxide (Pb3O4) or Lead Ortho-plumbate

We provide comprehensive (off the shelf) solutions for the manufacturing of Lead Oxides namely Lead Sub Oxide (Grey Oxide / Battery Oxide), Red Lead Oxide (Lead Tetra Oxide) & Litharge Oxide (Lead Mono Oxide / Lead Yellow Oxide) with the required process inputs.

Sub Oxide / Grey Oxide Plant

Grey Oxide is used on an extensive scale for preparation of plates in Lead Acid Batteries which requires production to strict specifications .Refined Lead (99.97% purity) ingots are the required input for our LSO manufacturing plant, which uses the ball mill process. It comprises of a small Lead Melting Furnace, operating in line with a hemispherical ball-casting machine, which feeds the balls to the ball mill .In the ball mill, Lead is converted to Lead Sub Oxide in an exothermic process, in conditions of a maintained temperature range of 135-145 degrees centigrade and constant airflow. The Grey Oxide is harvested through a high efficiency cyclone, bag-house filtration unit and induction draft fan arrangement. It is in a gray powder form. The desired particle size and free Lead content is ensured through proper plant configuration and precise control of ID Fan suction .Our Plant can produce up to 350 mesh size LSO powder, be configured for any desired production capacity and come complete with the required accessories & material handling systems.

Packing Specifications:

  • 25 Kg. Bag Packing
  • Box Packing
  • 1 MT jumbo bag packing

Uses of Lead Sub-Oxide / Grey Oxide:

  • Lead Acid Batteries
  • Electroplating Anode
  • Sulphuric Acid Tank Liners

Litharge and Red Lead Plant

Litharge, an important intermediate, is used in a variety of industries like ceramics and glass, lubricants and greases, insecticides, inorganic pigments, Lead soaps, petroleum refining, rubber and PVC. Red Lead is also used to a certain extent in the ceramics and glass, paints and pigments and explosives industries.

Litharge Manufacturing Plant

Our manufacturing solutions for Red Lead and Litharge have a Barton plant as the common first step. The required input is refined Lead ingots of 99.97% purity. The Barton plant output is routed to either the Red Lead or the Litharge furnace with their respective equipment complement. The Barton plant comprises of a small Lead melting furnace, operating inline with a Barton Reaction Pot with stirrers, classifier, cyclone, filter bag-house, ID Fan arrangement, together with a collecting bin and material handling systems.

The final Litharge plant module utilizes the Barton plant module output as its input. It comprises of the Litharge furnace, grinder, and cyclone and bag-house arrangements, ending in a mixer\silo & packing section.

Litharge, which is Lead Mono-Oxide (PbO) is a yellowish or reddish, odorless, heavy, earthy, water-insoluble, solid, PbO, used chiefly in the manufacture of Lead Stabilizers (Lead Steareates), pottery, Lead glass, paints, enamels, and inks. Litharge is also called Lead Monoxide, Lead Oxide, Plumbus Oxide.

Other use of Litharge is as intermediate used in a variety of industries like lubricants and greases, insecticides, inorganic pigments, Lead soaps, petroleum refining, rubber and PVC etc..

Our manufacturing Plant for Litharge has a Barton plant as the common first step. The required input is refined Lead ingots of minimum 99.98% purity. The Barton plant output is routed to the Litharge furnace with their respective equipment complement, which comprises of the Litharge furnace, grinder, cyclone and bag-house arrangements, ending in a mixer / silo, Pulverizer & packing section.

We are Manufacturing two type of Litharge:

  • Granular Litharge
  • Powder Litharge

Red Lead Manufacturing Plant

Red Lead is a bright red to orange-red powder, used Lead glass, and red pigments; a 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 the primer of choice 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 Lead is virtually insoluble in water. However, it is soluble in hydrochloric acid present in stomach, therefore it is toxic when ingested. It is also insoluble in alcohol. 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 has a Barton plant as the first step to produce messicot. 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.
