1. A sample of ilmenite (FeTiO3) analyzes 27.8% titanium and 35.4% iron. a. Which of the two elements is also likely to be found in the impurity materials in the sample? b. Based on the limiting element, what percentage of the sample is actually ilmenite? c. A 100 gram sample of the mineral is placed in a vessel containing 4.64 molality HF. The HF reacts with the FeTiO3 forming hydrogen gas and a solution containing TiF4, ferric fluoride and water. Write the reaction and determine how many liters of HF solution will be needed to complete the dissolution, using 30% excess. Given these conditions, what would the concentration of titanium in the solution be, in terms of grams per liter and mole?

Question
Transcribed Image Text:1. A sample of ilmenite (FeTiO3) analyzes 27.8% titanium and 35.4% iron.
a. Which of the two elements is also likely to be found in the impurity materials in the
sample?
b. Based on the limiting element, what percentage of the sample is actually ilmenite?
c. A 100 gram sample of the mineral is placed in a vessel containing 4.64 molality HF.
The HF reacts with the FeTiO3 forming hydrogen gas and a solution containing TiF4,
ferric fluoride and water. Write the reaction and determine how many liters of HF
solution will be needed to complete the dissolution, using 30% excess. Given these
conditions, what would the concentration of titanium in the solution be, in terms of
grams per liter and mole?
