In 2009 production of zinc reached 51,370t while lead and silver production was 25,894t and 1,356,003oz respectively. The mine concentrator treated 720,679t of ore to yield 759,395t of output. The average zinc grade was 7.3% and the lead grade 4%. The cash cost of production was approximately $0.26/lb, net of byproducts.
McArthur River Mine's success is a testament to the ingenuity of the local and Australian mining communities in developing technologies, solutions and efficiencies that transform our zinc and lead deposit into valuable products for everyday use.
In hard rock mining, much of the world's annual output of copper, gold and iron ore is won from open-pit operations. Other commodities produced from open-pit mining include diamonds, molybdenum, manganese, lead and zinc, uranium and a variety of industrial minerals, such as borates, talc and specialist clays.
Here are the five largest zinc mines by production in China, according to GlobalData's mining database.
Zawar Mine is one of the underground mining producing Lead & Zinc concentrates with long hole open stoping mining method, which is located at Udaipur, Rajasthan, India.
The lead produced from lead ore is a soft, flexible and ductile metal. It is bluish-white, very dense, and has a low melting point. Lead is found in veins and masses in limestone and dolomite. It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a co-product of zinc mining or a byproduct of copper and/or …

Today, Ireland is internationally renown as a major zinc-lead mining province. Over the last 40 years a string of significant base metal discoveries have been made, including the giant ore deposit at Navan (>70Mt). Zinc-lead ores are also currently exploited from two other underground operations in south-central Ireland: Lisheen and Galmoy. The combined …
This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task. This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore.
