Zinc
Cost, pure: $5.30 per 100g

Cost, bulk: $0.18 per 100g

Uses of Zinc
Zinc is used to galvanize iron to inhibit corrosion.

Zinc forms many alloys with other metals such as brass, German silver, nickel silver, typewriter metal and solders. Zinc alloys are used in die-castings for the car industry.

The metal acts as both the container and as an electrode in zinc-carbon batteries. The drawback of this dual use is that the electrode is consumed when the battery is in use, getting thinner until eventually the battery starts leaking.

Zinc is an essential trace element for animals and plants.

Zinc oxide, a white powder, is a versatile compound that has many uses.

It is used in sun block, make-up and in ointments such as calamine lotion.

It is also used in the rubber industry, concrete manufacturing and in paints.

Rhodium
Cost, pure: $13,000 per 100g

Cost, bulk: $7,000 per 100g

Uses of Rhodium
The majority of rhodium is used as a catalyst in catalytic converters. It is also used to catalyze industrial processes.

Rhodium is used as an alloying agent for hardening and improving the corrosion resistance of platinum and palladium.

As a result of its low electrical resistance, low and stable contact resistance, and its stability against corrosion rhodium is used as an electrical contact material.

The metal is used in jewelry and for decorations.

Iridium
Cost, pure: $4200 per 100g

Cost, bulk: $2300 per 100g

Uses of Iridium
The main use of iridium is as a hardening agent for platinum alloys.

With osmium, it forms an alloy that is used for tipping pens, and compass bearings.

Iridium is used in making crucibles and other equipment that is used at high temperatures.

It is also used to make heavy-duty electrical contacts.

Iridium was used in making the international standard kilogram, which is an alloy of 90% platinum and 10% iridium.

Radioactive isotopes of iridium are used in radiation therapy for the treatment of cancer.

Ytterbium
Cost, pure: $1400 per 100g

Cost, bulk: $ per 100g

Uses of Ytterbium
Isotope 160Yb is radioactive and is used in portable x-ray machines that need no electricity.

Under very high physical stress Ytterbium’s electrical resistance increases by an order of magnitude. It is therefore used in stress gauges to monitor ground deformations caused by earthquakes or underground explosions.

Ytterbium is used in alloys and is added to stainless steel to improve grain refinement and strength.

Ytterbium fiber laser amplifiers are used in marking and engraving.

Ytterbium compounds are also used as catalysts in the organic chemical industry.

Beryllium

Cost, pure: $748 per 100g

Cost, bulk: $93 per 100g

Uses of Beryllium
Unlike most metals, beryllium is virtually transparent to x-rays and hence it is used in radiation windows for x-ray tubes.

Beryllium alloys are used in the aerospace industry as light-weight materials for high performance aircraft, satellites and spacecraft.

Beryllium is used as an alloy with copper to make spark-proof tools.

Beryllium is also used in nuclear reactors as a reflector and absorber of neutrons, a shield and a moderator.

Tantalum

Cost, pure: $450 per 100g

Cost, bulk: $8.10 per 100g

Uses of Tantalum
Tantalum is used in the electronics industry for capacitors and high power resistors.

It is also used to make alloys to increase strength, ductility and corrosion resistance.

The metal is used in dental and surgical instruments and implants, as it causes no immune response.

Lithium
Cost, pure: $27 per 100g

Cost, bulk: $9.50 per 100g

Uses of Lithium
Pure lithium metal is used in rechargeable lithium ion batteries and the metal is used as an alloy with aluminum, copper, manganese, and cadmium to make high performance aircraft parts.

Lithium also has various nuclear applications, for example as a coolant in nuclear breeder reactors and a source of tritium, which is formed by bombarding lithium with neutrons.

Lithium carbonate is used as a mood-stabilizing drug.

Lithium chloride and bromide are used as desiccants.

Lithium stearate is used as an all-purpose and high-temperature lubricant.

It takes a civilized country to start addressing freedoms. Nyinyi ata constitution mlishindwa kupitisha.
Na usijifanye Tanzania hakuna maskini. Kenya GDP per capita - $1400, Tanzania - $800.
Kenya kuna many feet on the ground, many international organizations, lots of government mobilization, na ndio maana issue kama ya kiangazi hureportiwa sana.
Tanzania is still a dark country information-wise, lakini huwezi tudanganya kwamba nchi ambayo ni maskini kutuliko haina njaa.

Broo ur neither civilized nor rich...go back to school learn how to lie urself again

The Eden Garden was in Tanzania

The only seen and proven Garden to date is in Tanzania, where even the remains of the first human was found. It is the only place where you can see the true story of the beginning of human beings.
The Biblical Garden of Eden in Tanzania, Africa

Ok, so show me the flaming sword and the cherubim that was sent to guard that garden?

23 So the Lord God banished him from the Garden of Eden to work the ground from which he had been taken. 24 After he drove the man out, he placed on the east of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life.
