Most sand on the beach consists of grains of the mineral quartz (SiO2). Mineral sands are old beach sands that contain concentrations of the important minerals, rutile, ilmenite, zircon and monazite. These minerals are heavy and are also called 'heavy minerals'. But that is most and some sand contain other minerals,Hematite, also spelled as haematite, is the mineral form of iron(III) oxide, one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils
The Democratic Republic of Congo declared cobalt and coltan strategic mineral. The Democratic Republic of Congo has declared cobalt and coltan strategic mineralresources. ... Cobalt and coltan are used in the production of electric vehicles, electronic devices, and renewable energy technology.
Coltan. Coltan is short for columbite-tantalite, a dull metallic ore. When refined, coltanbecomes a heat resistant powder, metallic tantalum, which has unique properties for storing electrical charge. ... Pegmatites contain many rare metals, as well as enormous crystals of some common minerals.
Could weed simply just stop buying from these areas, or China who buys these things illegally. It just came to my intentions over 35 years ago set every country could mind their own resources but it's a dirty job. And no one wants to work like the people in the videos using shovels, this is where the prices go outrageous, yes cheap labor is why we're in this predicament. But this careers for people who need money and they want to know where to get it free. Being a money specialist, it's what you walk over everyday it's all around you and you just have to have the knowledge to get what you need and sell it not just one element but all types can change your pocketbook for the better, let's look at all the minerals that are magnetic. And can be picked up with a magnetic sweeper!
The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.
Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions. Iron is found in two principle ionic states called ferrous and ferric ions. The ferrous ion has charge of positive two, (+2); the ferric ion has a charge of positive three, (+3). The two ions have different atomic radii because the higher charge of the ferric ions pulls the electrons surrounding the ion in tighter. This fact can lead to the different ions being placed in separate positions in a crystal structure. Electrons that move from the ferrous to the higher positively charged ferric ions create a slight magnetic field.
The minerals that are magnetic range in magnetic strength from being capable of lifting steel rods to barely turning the needle on a compass. A few minerals may not be magnetic, but are still attracted to magnets. Magnetism is somewhat of an unreliable property as not all specimens may demonstrate it. While the presence of magnetism may all but clinch an identification, the lack of magnetism should not generally exclude typically magnetic minerals. A compass needle is a good test device for testing magnetism as is a magnet on a string that might sway near the specimen.

Magnetite is an oxide of iron (as is hematite). It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
Magnetite is a natural magnet, hence the name, giving it a very nice distinguishing characteristic. Explaining the magnetism is not easy but here is a go at it. Remember, electricity produces magnetic fields just as magnetism produces electric fields. Magnetite is a member of the spinel group which has the standard formula A(B)2O4. The A and B represent usually different metal ions that occupy specific sites in the crystal structure. In the case of magnetite, Fe3O4, the A metal is Fe +2 and the B metal is Fe +3; two different metal ions in two specific sites. This arrangement causes a transfer of electrons between the different irons in a structured path or vector. This electric vector generates the magnetic field.
Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids).
Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.
The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS₂. Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.
