Single-pass flow-through leach test (source code)

= Single-pass flow-through leach test

= SPFT leach test
{synonym}

A continuously refreshed leach test used to measure dissolution under controlled dilute conditions. At steady state the elemental normalised rate is $r_e=Q(c_{e,\rm out}-c_{e,\rm in})/(f_eS)$. Varying $Q/S$ helps identify solution-affinity effects.
