· In the processing of various iron ores, the resulting IOTs demonstrate a diverse phase composition, often influenced by the presence of low-grade goethite-hematite ore and associated clay minerals. The phase composition of IOTs, as presented in Table 2 , varies significantly due to the diverse mineralogy inherent in the iron ore extraction

· Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce 100% fine product.

I'm having this problem too. It seems to be an issue with this mod. Try loading ore one at a time, not whole stacks. Also don't break the structure (this will delete the ore inside). Try using a redstone lever to turn it off and on. Also try putting in another type of ore. One of these or some combination should work. 2.
