Close to 85% of all products using lead metal are recyclable. One direct consequence is the continuously rising recycling rate of lead-bearing scrap. In 1999, refined lead recovered fijom secondary materials totaled 2.9 million tonnes, equivalent to 47.2% of total production worldwide or 58.9% in the Western World (4). Total refined lead metal supply rose in 1999 to 6.143 million tonnes. Of this, 4.93 milUon tonnes were produced in Ae Western World. Considering that the bulk of the lead from secondary materials is still recovered in the Western World, approximately 2.2 million tonnes of lead from primary sources was produced in the Western World. As shown in Table II, significant increases in production were noted at Pasminco s Port Pirie operation, in Kazakhstan as a result of increased output of the Ust-Kamenogorsk smelter and fix>m China.

COMMISSIONING AND OPTIMISATION OF THE NEW LEAD AND SILVER REFINERY AT THE PASMINCO PORT PIRIE SMELTER... 

Pasminco Port Pirie Smelter is part of the Australian company Pasminco which was formed in 1988. It has a smelting and refining history based on the discovery of the rich lead, zinc and silver deposits at Broken Hill, Australia, over 100 years ago.

Pasminco s Kroll-Betterton antimony debismuthising plant has been in operation for almost 20 years and the process has been well documented. The upgrade was carried out simultaneously with the batch refinery stages. Modifications to kettle size, burner control systems, and equipment used to dissolve the calcium and magnesium reagents and to remove the bismuth crusts have all enhanced the ability of the plant to run at the design rate of up to 40 t/h, and remove bismuth fi om input bullion at 0.05-0.06% down to <0.005% Bi.
