An ore shoot is a hypogenic mass that is deposited in veins within a planar channel or lode, found in a shear or fault zone, fissure or lithologic boundary. [1] The ore shoot is the area of concentration which contains a primary ore along the veins present in the rock, and consists of the most valuable part of the deposit.

Galena is the main ore of lead, used since ancient times, [7] since lead can be smelted from galena in an ordinary wood fire. [8] Galena typically is found in hydrothermal veins in association with sphalerite, marcasite, chalcopyrite, cerussite, anglesite, dolomite, calcite, quartz, barite, and fluorite.
Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a chemical reaction.
The formed carbon monoxide (CO) is flushed away in the fumes, while steel is formed. To increase the oxidizing power of the "heat", more iron oxide ore can be added. [4] The process is far slower than that of the Bessemer converter and thus easier to control and sample for quality assessment. Preparing a heat usually takes eight to eight and a ...
Superheating can occur when an undisturbed container of water is heated in a microwave oven.At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm.
