Filtered Tailings Move From Option To Expectation
Dam failures turned tailings from an engineering question into a board-level solvency question, and the industry standard published afterwards made filtered dry stacking the default assumption on newly permitted facilities rather than one option among several. Adoption on new permits now sits near 38%. Filtration is capital and energy intensive and does not pay back in any conventional sense, which is precisely why the sponsoring function inside the mine is never operations. Suppliers who present delay risk rather than payback are writing the paper the sponsor needs. Finance departments keep asking for the other one.
