In the background, two miners examine the roof of the mine. From the beginning, lead and zinc mining in the Joplin district was a dangerous means to make a living, and if lucky, a fortune, too. The year 1910 was considered a good one, respectively, when compared to 1909 when 51 miners lost their lives.
The Tara lead and zinc mine is located at Navan, County Meath, approximately 50km northwest of Dublin. The mine opened in 1977, was acquired by Outokumpu in 1986 and in January 2004 was transferred to New Boliden as part of an asset exchange between the two Nordic companies. Placed on care-and-maintenance in 2001 …
In this study, sulfuric acid leaching and gravity shaking-table separation by shaking a table are used to extract lead and zinc from a Pb-Zn oxidizing roasting cinder.
