More DetailsCassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek "kassiteros", meaning tin.
More DetailsOre is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
More DetailsCassiterite is a tin oxide mineral, SnO 2. It is a reddish, brownish, or yellowish mineral consisting of tin dioxide. It is the main ore of tin. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. It is a black mineral is a member of rutile group and an important ore of tin.

More Details· An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.
More DetailsCassiterite is an economically important mineral, being the primary ore of the metal tin. It is also used as a collectors mineral with the transparent forms being highly desired. Occurrence and Properties of Cassiterite – Most sources of cassiterite today are found in alluvial or placer deposits containing the resistant weathered grains.
More DetailsMany different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
