No Slide Title

A 3.33 g sample of iron ore is transformed to a solution of iron(II) sulfate, FeSO4, and this solution is titrated with 0.150 M K2Cr2O7 (potassium dichromate). If it requires 41.7 mL of potassium dichromate solution to titrate the iron(II) sulfate solution, what is the percentage of iron in the ore?

Sampling of run-of-mine mill feed— A practical approach

The first sample was a low-grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm. The second sample consisted of boulders of high-grade gold ore (about 60 g/t) that were crushed to yield a 95% -12 mm product. The masses of each of …
