Some plants find it beneficial to use a visual sampler on the lead tailing ahead of the zinc circuit. The Visual. General view of the flotation section at a modern silverleadzinc mill. The lead circuit is on the left and the zinc circuit is on the right. Sampler is also useful for evaluating the lead or zinc concentrate.

Soil sampling and characterization. A soil, which was classified as a Technosol (IUSSWRB, 2014), was sampled in a former zinc mining area in Vazante (Minas Gerais; 17° 55′ 43″ S, 46° 49′ 15″ W), in an opencast mine whose operation discontinued for more than 15 to Köppen classification, the climate is "Aw," characterized by a long period with low rainfall.

Judd's start with the mines came in the late 1940s, which was very near the end of the town's lead and zinc legacy. At the time, Granby's operations were part of the TriState Mining District, an area that the Missouri Department of Natural Resources defines as around 55 miles between Kansas and Lawrence County, and 30 miles from Neosho to the north fork of the Spring River.
