WHAT DO WE IMPORT ?

We continuously welcome prospective suppliers who could cater for our this demand and get into long term agreement.

We import :

Battery Plate Scrap

Specify whether automotive, industrial or mixed. Also whether they are groups or loose. The only other metallic that might be included could be Lead Connectors. To be free of non-metallic, i.e., plastic or rubber, with the exception that separators may be included. Material to be dry. May be bought on an assay basis or a flat price. Submarine plates subject to negotiation. Review packaging specifications and regulatory status pertaining to shipping with buyer prior to sale.


Lead Scrap

Shall consist of clean soft scrap Lead, free of other materials such as Lead drosse, battery plates, lead covered cable, hard lead, collapsible tubes, foil, type metals, aluminum, zinc, iron and brass fittings, dirty chemical lead and radioactive materials. Review packaging specifications and regulatory status pertaining to shipping with buyer prior to sale.

Lead Ash

Should be clean and reasonably free of other materials such as iron, dirt, harmful chemicals or other metals. To be free of radioactive materials, aluminum and zinc. May be bought on an assay basis or as agreed to by buyer and seller. Other metals present such as antimony, tin, etc., to be accounted for as agreed between buyer and seller. Material to be readily dumped from drums. An extra charge may be assessed if material has to be mechanically removed. Review packaging specification and regulatory status pertaining to shipping with buyer prior to sale.

Lead Residues

Dry Battery Scrap

To be free of any liquid. Cases to be either plastic or rubber and be complete including caps. Non-lead (ni-cad, ni-fe, carbonaire, etc.) not acceptable. Industrial steel cased, aircraft (aluminum cased) and partial, cracked or broken batteries and batteries without caps subject to special agreement. Review packaging specifications and regulatory status pertaining to shipping with buyer prior to sale.

Lead Ore

Any of several minerals from which Lead is extracted. The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time and zinc, which can cause problems during smelting.

The Sulfide Mineral, Galena, a Lead sulfide, PbS, is the most important ore mineral of Lead. It can contain 86% Lead. Its metallic, Lead-gray cubic crystals (isometric system) and cubic, perfectly cleavable masses are distinctive and characteristic. Hardness is 2.5, streak Lead gray, and specific gravity 7.4-7.6. Galena is a widespread mineral deposited by hydrothermal solutions as large, irregular masses in dolomitize limestone and in zones of contact metamorphism and as veins in volcanic rocks. It often contains enough silver to be mined as a silver ore.

Most commercial deposits of Lead ore are in the form of veins, where hot fluids have leached the ore from cooling igneous masses and deposited it in cracks in the surrounding country rock, and in thermal metamorphic zones, where the heat of igneous intrusions has altered the minerals of surrounding rocks. Lead is mined in over 40 countries, but half of the world's output comes from the USA, Canada, Russia, Kazakhstan, Uzbekistan, Canada, and Australia.

Lead Concentrate

Ore is recovered by blasting then dumping, followed by crushing and finally hoisting to the surface for treatment. In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then treated using extractive metallurgy. The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate. The concentrate, which can range from 50% to 60% Lead, is dried and then treated using pyrometallurgy. The concentrate is sintered before being smelted in to produce a 97% Lead concentrate. The Lead is then cooled in stages which causes the lighter impurites (dross) to rise to the surface where they can be removed. The molten Lead bullion is then refined by additional smelting with air being passed over the Lead to form a slag layer containing any remaining impurities and producing 99.9% pure Lead.
