Please stop smoking and sniffing too much otherwise you will get paranoid and hallucinated as usual, becoming too envious and too jealous so as to see what is not visible and hear what is not audible, talking pure garbage with out any evidence just to spread fake news hoping to create division and wounding the grand Ethiopian vision.

Do not forget that ታከለ ኡማ is Boss of all Ethiopian precious natural resourses such us Gold, siliver, tantalum, Opal and many others!!
By the wayway, do you know that Ethiopia is the sixth biggest producer of tantalum in the world?

Tantalum: Properties & Applications
Blogs - March 30, 2021
Tantalum is one of the rarest elements on earth in both pure and alloy forms. At the same time, it is needed in a wide variety of applications. First discovered in 1802, it was originally thought to be a niobium allotrope which is chemically similar to tantalum. However tantalum was determined to be an element of its own, one of the most corrosion-resistant metals available, with a rarity similar to that of uranium.
Chemical Properties of Tantalum
Atomic Number 73
Atomic Mass 180.94788 u
Density 16.6 g/cm3
Melting Point 3,017 °C
Co-efficient of Thermal Expansion 10-6/K
Tantalum Properties
With its grey finish, tantalum is similar in color to platinum. It has a density of 16.6 g/cm3; double that of steel. It is highly ductile at room temperature and has the fourth highest melting point of all known metals at 3017°C (5463°F).
Tantalum is used in a wide range of alloys to increase strength, ductility, and melting point. Tantalum can be used in a range of forms suited to different industrial applications such as powder which can be used in electrical capacitors and sheet to line columns and vessels in chemical applications, and as vacuum furnace parts. When it is drawn into a thin wire, tantalum is used as a filament for metals which evaporate such as aluminum. In addition to these forms, tantalum can also be used as rods/wires, tubes, strips, foils, and oxides.
Tantalum Applications
Chemical Processing
Tantalum has excellent corrosion resistance to most acids (a notable exception is hydrofluoric) in a wide range of concentrations and temperatures. Its corrosion resistance is similar to glass in many of these acids. Consequently, it is used in chemical processing equipment where hot, highly corrosive environments are encountered. Heat exchangers, bayonet heaters, tank liners, valve liners, feed lances, rupture disks, and various other components are fabricated from tantalum.
Semiconductors
The semiconductor market is built on the foundation of silicon chip manufacturing technology. Integrated circuits (ICs) are produced with nanoscale feature sizes and the optimization of electron conduction between nanometer-scale features is critical. Tantalum can be used in logic chips and DRAMS to facilitate the use of copper as interconnects as, unlike copper, tantalum atoms do not diffuse into silicon at the temperatures these chips operate at.
High-purity tantalum and tantalum nitrides are grown on top of the copper chips to stop electromigration of the copper atoms, meaning the semiconductor devices remain reliable for longer. At H.C. Starck Solutions, we supply sputter target blanks which are often used to generate barrier layers in modern ICs.
Medical Equipment
Tantalum is extremely biocompatible and does not produce toxic products or trigger adverse immunological responses when exposed to body or bodily fluids. This means that tantalum works well for medical applications that require pairing with living tissue such as medical implants and prosthetics.
Military and Aerospace
Nickel based superalloys are used extensively in gas turbine engines for commercial and military aircraft where they are exposed to extremely high temperatures and stresses. Tantalum additions to these superalloys help improve high temperature strength. Parts and components made from these tantalum containing superalloys can operate at higher internal combustion temperatures resulting in enhanced thrust efficiencies and lower fuel consumption.
Furnace Applications
Refractory furnace trays and boats are routinely used to hold semi-finished goods during extremely high temperature processes like sintering. Tantalum is an exceptional material for furnace applications, retaining good dimensional stability at process temperatures with excellent resistance to creep deformation ensuring long service.
Nuclear Applications
Superconducting wires intended for use in nuclear applications often incorporate tantalum diffusion barriers designed to resist internal diffusion and impart enhanced mechanical properties to the superconducting element. This is useful for large-scale scientific initiatives such as nuclear fusion research.
Electronics Industry
Tantalum has exceptional storage capacities with the ability to store more charge per gram than any other comparable metals. For this reason, tantalum is well-suited to the production of electrical capacitors and resistors whilst being able to hold large amounts of charge in a small component. This has meant manufacturers have been able to make electrical parts and devices much smaller.
H.C. Starck Solutions can provide excellent assistance in the application of ready-made and proprietary parts using pure tantalum and tantalum alloys. Contact the team today, to find out more.

I wonder if there is data on the current export quantity and financial amounts.

Umma and Takele are natural resource and finance ministers. It was under their watch Borena's cattle's millions died most smuggled to Arabs. Borena has been starved these hero peoples. Most natural resources are in the hands of foreigners. As for Daniel Kibret, he is not money person he is deakon. Aby is trying to corrupt him but Daniel taking the position for the love of his country.

Be careful what you wish for about natural resources. It is a curse and nothing to be proud of . Raw and final product of natural resources will never utilize of make origin nation of natural resource but Western and China. You will be like Congo or S Africa laborer and slave collecting the resources and the corrupt government just to pocket what it gets from the foreigners.
