Hi all Find very very useful information about precious metal recovery on GRF thanks for all members and forum to support me Now i am with new query about tantalum capacitor I'm trying to recover tantalum from SMD Ta cap There are two valuable metal silver and mainly ta. Silver on cooper coated and ta in Tantalum anode like wire. First …

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that …

Sep 12, 2019. #8. The file is legitime. An interesting graduate student work on how to refine tantalum into pure tantalum powder. Maybe not how it is done today, but some interesting chemistry. For example reducing tantalum oxide into tantalum powder in a magnesium atmosphere. I'm about halfway through the article and it's going into my …

Tantalum powder is a fine, grayish metal powder derived from tantalum, a rare and dense transition metal found in nature. It is often used as a key ingredient in various alloys and compounds due to its remarkable properties. Tantalum is known for its high melting point, excellent corrosion resistance, and biocompatibility, making it a …

Furthermore, the sourcing and refining of tantalum must be done with care to avoid unintended support of conflicts, especially in regions where mining profits contribute to ongoing tensions and violence. Thus, your awareness of tantalum's sourcing can play a critical role in promoting responsible consumption and ethical sourcing practices.

Does anybody do anything with tantalum other than just collecting it? I am curious as to if it is worth messing with, as I have seen that there are some...

Foreign investor Macedonian company Power Resource Group, made an investment worth $12 million (Rwf10 billion) with RDB for the construction of the tantalum refinery in the Eastern district of Rwanda. This will be the country's only mineral refinery, serving in place of Phoenix Metals — a tin refinery in Karuruma, Gasabo District — …

The purity of the refined tantalum scraps was improved up to 5N (99.9991%) from 4 N (99.996%) of the initial tantalum scraps. The amount of metallic impurities in the tantalum was decreased from ...

Abstract. On-going technological developments, especially in the field of microelectronics and communication have reflected in concomitant increase in the demand for strategic metals such as tantalum (Ta) and niobium (Nb). The extraction of these two metals from ore deposits and secondary resources is based on the generic extractive ...

the Earth's crust is 0.7 parts per million. Tantalum does not occur naturally as a free metal; however, tantalum occurs in a range of oxide mineral species, including ixiolite, microlite, tantalite, tapiolite, and wodginite. Tantalum-bearing mineral deposits are found in igneous rocks, which include carbonatites,

I have several pounds of tantalum caps I've been collecting. I bought a CD about precious metal recovery on Ebay a few years ago, and it mentioned tantalum caps as an overlooked source of income from scrap boards. Apparently there was a large spike in the price of tantalum back around 1979-1980 when it was in the $200 range?

The process of scrap recycling of refractory elements (e.g. tantalum), reactive metals elements (e.g. titanium) and alloys through electron beam method results not only in reducing the scrap quantity but also in reuse of these expensive metals and alloys with unique properties. The world's recourses of these metals are exceedingly limited.

Processing: extraction and refining. The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to ...

Tantalum Refining. Tantalum has many diverse uses and so the supply chain that feeds these final products is complex. Mining for …

Tantalum's role in power supply units. Every major electronic device needs a power supply unit (PSU) – a bridge between the device and the electrical outlet. Tantalum's consistency and reliability make it a top choice for PSUs, ensuring that they deliver the right amount of power without overheating or failing.

A surface-mount Ta capacitor consists of a porous, high-surface anode of sintered tantalum powder (Ta-anode) surrounded by tantalum pentoxide (Ta 2 O 5) as a dielectric, manganese dioxide (MnO 2) as a cathode, a carbon layer preventing reaction between MnO 2, and a silver layer that connects the cathode with a lead frame and a …

cases, tantalum minerals are separated from the concentrate using a dry method. Most of the tantalum, how­ ever, is smelted along with tin ore concentrate and then enriched in a …

Tantalum compounds are relatively unimportant commercially, although the carbide TaC is used in cemented-carbide …

Regarding the tantalum refining industry, in 2014, there were 48 tantalum refining facilities among 12 countries in the world, while 19 of them were in China. China …

According to a report from the US Geological Survey, the source of tantalum has dramatically changed over the past few years. In 2000, Australia produced around …

Tantalum. Ekeberg isolated tantalum from Swedish ores in 1802 and gave it its name, that of the son of Zeus and the father of Niobé. Separation from niobium, with which it is always associated in ores, proved very difficult, being achieved by Marignac only in 1866. In 1903 von Bolton succeeded in producing tantalum powders by reduction of the ...
