Tantalum is a rare mineral essential for making capacitors for devices like smartphones and laptops. A small region of Africa produces 60% of the world's supply, with Rwanda as the main exporter. But tantalum was sometimes smuggled in from conflict-ridden Congo, where it was mined by children or workers enslaved by warlords.
E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium (Pd) and platinum (Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components.

Tantalum was discovered in 1802 by A.G. Ekeberg in Uppsala, Sweden. Tantalum is a shiny, silvery colored metal which is heavy, dense, malleable and ductile when pure. It is found in small quantities in minerals (generally in conjunction with niobium), and is isolated by conversion to the oxide and then the fluoro-complex, K 2 TaF 7, from which ...

The typical gold content of the incoming gold alloys is about 50-99 % (initial purities below this value will reduce the production capacity) with a maximum Silver content up to 20% by feeding thin powder (normally the max content of silver is 12-13 % by feeding grain). EFZERO gold refining plant can be fed with grain or better with thin powder (150-600 micron). The powder is the most ...

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.
The refining of tantalum from its ores is one of the more demanding separation processes in industrial metallurgy. The chief problem is that tantalum ores contain significant amounts of niobium, which has chemical properties almost identical to those of Ta. A large number of procedures have been developed to address this challenge.

Anyone happen to know if any of these might contain Au, Ag, Pt, Pd, or Ta? You can just say which PM, or if it's "junk" I'll be clipping the legs for scrap copper before processing anything. I have a few pounds of each if that makes anything more worthwhile to process. Left side, besides...
Tantalum is a sensible choice whenever high corrosion resistance is required. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance. In addition, tantalum is very easy to work at well below room temperature despite its …

A process to chemically refine and consolidate tantalum, niobium and their alloys to a fabricated product of net shape or near-net shape with higher throughput, more consistency, and lower manufacturing costs compared to prior art routes or rejuvenate damaged and deteriorated refractory metal parts. Powder metal is loaded into hoppers to be fed into laser forming/melting equipment.
Thus it is ideal for remelting and refining of metals and alloys under high vacuum in water cooled, ceramic free copper molds. Today the process is mainly employed for the production of refractory and reactive metals (tantalum, niobium, molybdenum, tungsten, …
