Tantalum mining technique blasting, crushing, transporting tantalite ore
Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated through ...

Production of Platinum and Palladium – Two of the Rarest Platinum …
The extraction process of palladium is very similar to that of platinum, as these two metals are naturally occurring in the same ore deposits of the earth's crust. So, it follows the initial step of refining palladium-containing ores by crushing the ore and immersing it in reagent with water. This process is called "froth flotation.".

Gold Extraction & Recovery Processes
Cyanide solution percolates through the heap leaching the gold and silver and is collected on the pregnant solution pad. The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation.

The screening process. The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to 1.3 cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.
