Igneous rocks can have sparkly minerals like quartz. If your rock has layered or banded patterns, it might be metamorphic. Sedimentary rocks, meanwhile, can have layers that look like pages in a book. Knowing the rock type helps because some minerals are mostly found in one type. For example, olivine is common in igneous rocks.

Fluorescent lamps can be used in underground mines to identify and trace ore-bearing rocks. They have also been used on picking lines to quickly spot valuable pieces of ore and separate them from waste. Many gemstones are sometimes fluorescent, including ruby, kunzite, diamond, and opal. This property can sometimes be used to spot small stones ...

Hemimorphite is a zinc-bearing mineral that's found in many parts of the zinc-lead belt. It's a zinc silicate mineral, with a white, yellow, green, or blue color. It's actually a side effect of the oxidation of the zinc-bearing ore sphalerite. It mainly occurs in the upper layers of the zinc-rust belt where the mineral was exposed to oxygen.

Quartz is classically aligned with gold.The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz. It's universally considered the richest of the gold ores …
A dataset of global zinc-bearing mineral deposits has been developed that complements previous such datasets (Franklin et al., 2005; Meinert et al., 2005; Mosier et al., 2009a,b; Taylor et al. 2009). The new dataset provides information on name, location, type, metal endowment, host rocks, associated igneous rocks, regional and proximal alteration …
Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that have a vitreous or pearly luster and …

The 1870 discovery of zinc ore near Galena, Kansas, marked the beginning of a century of lead and zinc mining in the Kansas part of the Tri-State mining district (fig. 1). The Tri-State was one of the major lead and zinc mining areas in the world and included parts of southeastern Kansas, southwestern Missouri, and northeastern Oklahoma.

tons, respectively [12]. The content of Zn in natural zinc ores in China is 8%–20% which is close to that in the zinc-bearing dust [13–15]. Therefore, the zinc-bearing dust produced in iron and steel enterprises can be reused as high-quality raw materials to produce metal Zn. In addition, relevant reports indicated that the world's
Common metamorphic rocks at various degrees of metamorphism. Pictures & Descriptions of Metamorphic Rock Types. There are so many types of metamorphic rocks that it can be hard to keep track of them all, but thankfully things are made a little easier by dividing them into two general groups – foliated and non-foliated (or granular).
