2000 – The process of desulphurization of the lead battery paste is tested and applied on several plants. 2002 – Engitec enters in Joint venture with Ecometal (Estonia) for the realization of a new battery processing plant. 2006 – Engitec R&D Company is incorporated into Engitec Technologies
Lead processing | Britannica· Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy5-10 ton per hour automatic battery (LAB) .5-10 ton per hour automatic battery (LAB) crushing and separation machine. Input and Output. This system is suitable for the Lead acid battery with the diagonal dimension less than 800mm. By crushing and separation process, we can produce 6 products as shown in below diagram:
Health hazards of China's lead-acid battery .This paper is the first to integrate the market factors, production processes, and health impacts of China's growing lead-acid battery industry to illustrate its vast public health consequences. The implications of this review are two-fold: it validates calls for a nationwide assessment of lead exposure pathways and levels in China as well as for a more comprehensive investigation into the ...

Recycling used lead-acid batteries - WHOThe document outlines the process of recycling used lead-acid batteries and describes how lead exposure can occur. Three case studies illustrate the impact that uncontrolled battery recycling can have on a community. The document then discusses the adverse health impacts resulting from exposure to lead.
Lead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.Charging and Discharging of Lead Acid Battery - .Discharging of Lead Acid Battery When the sulphuric acid is dissolved, its molecules are dissociated into hydrogen ions (2H +) and sulfate ions (SO4 – –) which moves freely in the electrolyte. When the load resistance is connected to terminals of the battery; the sulfate ions (SO4 – –) travel towards the cathode and hydrogen ions (2H +) travel towards the anode.Lead: Battery Manufacturing eTool - Oxide and .· Lead oxide, which is used to create the paste used on the battery plates, is either produced by the Ball Mill Process or the Barton-Like Process.It may also be purchased from an oxide producer (see receiving). The major source of lead exposure in the oxide production process comes from leaking equipment and system upsets.Lead: Battery Manufacturing eTool - Oxide and .During the paste mixing process, lead oxide, water, acid, and other chemicals are blended in a mixer to form a thick paste. The major source of lead exposure in this process is from lead oxide that escapes from the paste mixing machine, dries, and becomes airborne. or mixer door seals. Ventilation ...
