6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Developments in Milling Practice at the Lead/Zinc

Figure 5 Zinc circuit laboratory flotation performance of different ore types. Zinc metallurgical performance (Figure 5) varies over a smaller band, due to low zinc losses in the lead circuit and the ability to be more selective against pyrite. The methods used in the laboratory have shown good agreement with plant performance and provide

Stabilization of lead and Zinc Flotation Circuits

Galmoy Mine, owned by Arcon Mines Limited, has operated since 1997, and is one of three operating lead/ zinc mines in Ireland. Changes in ore type starting in mid 2002 created challenges to metallurgical operations at Galmoy. This resulted in unacceptable lead and zinc flotation performance, which prompted initiation of a
