The turf, when fresh cut, has its fibre broken up as far as possible, and is then placed between cloths, and pressed by a hydraulic press of great power. The condensation is to about one-third of the volume, and it loses about two-fifths of its weight, by the water, which is forced out in the pressing, and subsequently dried out.

Bismuth: extraction-Metalpedia

Bismuth is extracted from its ores by dry, wet, or electro-metallurgical methods, the choice depending upon the composition of the ore and economic conditions. The dry process is more frequently practised, due to the easy reducibility of the oxide and sulphide, together with the low melting-point of the metal, which renders it possible to effect a ready separation of the metal from the gangue and impurities.

how is copper concentrate process

Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace.

Haematite deposits of Cumbria

The Cumbrian deposits are composed almost exclusively of haematite but in a variety of forms. Compact, massive haematite is most abundant, but the area is famous for the fibrous mammillated variety known as ''kidney ore'' (P220237), the distinctive conical broken fragments of which are termed ''pencil ore''.

As broken ore is removed from the mining level of the ore column, the ore above continues to break and cave by gravity. The term "block caving" probably originated in the porphyry copper mines, where the area to be mined was divided into rectangular blocks that were mined in a checkerboard sequence with all the ore in a block being removed before an adjacent block was mined.
