Refractory (planetary science) - Wikipedia

In planetary science, any material that has a relatively high equilibrium condensation temperature is called refractory. The opposite of refractory is volatile.The refractory group includes elements and compounds like metals and silies (commonly termed rocks) which make up the bulk of the mass of the terrestrial planets and asteroids in the inner belt.

Diagnostic Leaching for Refractory Gold Ores - SRK

Diagnostic Leaching for Refractory Gold Ores. A diagnostic leach test can be very useful to qualitatively assess how gold occurs within the ore and the extent to which it may be refractory. Several different permutations of diagnostic leach tests depend on specific objectives, but they generally involve the sequential leaching of a gold ore
