What factors would have to change for a mineral to be considered an ore?

What factors would have to change for a mineral to be considered an ore?

Ore minerals Concentrating processes, which are based on the physical properties of the mineral, include magnetic separation, gravity separation, and flotation. The second factor is smelting—that is, releasing the metal from the other elements to which it is chemically bonded in the mineral.

What is an ore quizlet?

Ores. Are naturally-occuring materials that can be profitably mined. It can be mineral or rock or metallic or nonmetallic. Deposit.

How do ores form?

Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly-created igneous rock. Minerals found in such rock might include feldspar or mica.

How concentrated must a metal be in order to be considered an ore?

An ore is a rock in which a valube or useful metal occurs. Copper may be inriched 100 times relative to average rock , while mercury (average concentration 80pbb) must be enriched to about 25,000 times its average concentration before the ore is rich enough to be mined profitably.

What is an ore deposit What factors determine whether a mineral deposit is profitable to mine?

Geologists study geological formations and then test the physical and chemical properties of soil and rocks to locate possible ores and determine their size and concentration. A mineral deposit will only be mined if it is profitable. A concentration of minerals is only called an ore deposit if it is profitable to mine.

What is the difference between an ore and a rock?

Rocks- A rock is made up of 2 or more minerals. Ore- A mineral occurring in sufficient quantity and containing enough metal to permit its recovery and extraction at a profit. Or, a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted is an ore.

Which nonmetal is used for food?

Nitrogen
(i) Nitrogen is used for preserving food materials because of its inert behaviour.

What are ores give example?

Ores are minerals that have a high concentration of a certain element, typically a metal. Examples are cinnabar (HgS), an ore of mercury, sphalerite (ZnS), an ore of zinc, or cassiterite (SnO2), an ore of tin (Mineral). Part A: The table lists several ores of metals and their chemical formulas.

What are ores Class 5?

Answer: Ores are minerals that have a high concentration of a certain element, typically a metal. Examples are cinnabar (HgS), an ore of mercury, sphalerite (ZnS), an ore of zinc, or cassiterite (SnO2), an ore of tin (Mineral).

What makes a mineral different from a rock?

Minerals are inorganic, crystalline solids that occur during biogeochemical processes in nature like in cooled lava or evaporated sea water. Minerals are not rocks, but are actually the components that make up rocks. Though they vary in color and shape, each mineral has a distinct chemical composition. Naturally

How are minerals classified according to their chemical composition?

A rock, on the other hand, does not have a specific chemical composition because it is a composite of a variety of minerals. Minerals are classified based on their anionic group. The major mineral groups are native elements, sulfides, sulfosalts, oxides and hydroxides, halides, carbonates, nitrates, borates, sulfates, phosphates and silicates.

When do you know a mineral is a solid?

Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness, all minerals are a solid at a given temperature. If a substance is not in its solid state, it is not currently a mineral.

Which is not a mineral at a given temperature?

Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness, all minerals are a solid at a given temperature. If a substance is not in its solid state, it is not currently a mineral. For example, ice is a mineral, but liquid water is not.
