Investing in potash: What is potash and what is potash
Most potash reserves were deposited in inland oceans which evaporated to leave behind potash ore beds. These were subsequently buried deeply under earth and are now the main sources of mined potash. While potash is abundant in the earths crust, nearly all the worlds potash supply is controlled by thirteen companies in twelve countries.

A Look at FEECOs Capabilities in the Heap Leaching Industry
Agglomerators are an essential part of any large scale leaching operation. Without drums, non-agglomerated ore fines tend to be irregular in shape, impeding a consistent flow of leaching solution through the ore heap. Consequently, less ore is leached and the process cannot achieve its full potential.
