the brassware industry were moulding and polishing. The child was employed to do two types of jobs. He rotated the wheel‚ which was called pankha (hand wheel) to keep the furnace fire burning and the temperature in the furnace was about 1100° C. The child also checked the molten metal by opening the top of the underground furnace. Consequences: In these processes there was not only danger of getting badly burnt‚ but he also inhaled the fumes and hazardous gases. Lead and Zinc poisoning were the

Mobile Phones Introduction: Mobile Phones were first created in 3rd April 1973 by a man named Martin Cooper‚ it is now 2013‚ and approximately 1 billion phones are being made and sold per year. Because of this‚ the demand for minerals to create mobile phones‚ is becoming more than ever. One of the main minerals used in creating mobile phones‚ is tin. Tin is generally used as the basic outside structure of a mobile phone. This essay will conduct of several topics‚ such as location of minerals‚ the

calcined limestone. (Li et all). This work covers and presents a multi experimental test of preparing the modified CaO through hydration of water/ethanol by manipulate various parameter combination. The experiments were conducted using a modified furnace to permit the flow of CO2 for carbonation process and calcium oxide. Then‚ the carbonation conversion is calculated which signify the effectiveness of CO2 capture and the optimum parameter to produce the highest carbonation conversion is identified

In order to isolate the metallic lead from this mixture‚ these materials are charged into a furnace together with appropriate fluxes & reluctant‚ drowses‚ returning slugs and process dusts for smelting. Off-gases from the smelting furnace are filtered and the dust collected is returned to the furnace. The metal tapped from the kiln is transferred to refining process and treated to produce commercial quality lead. From: http://www.berzelius
