The Blackrock Project has the capability to produce two forms of commercial titanium feedstocks; ilmenite concentrate and commercial titanium slag.
Ilmenite concentrate is a raw material that contains titanium dioxide (TiO2) and the BlackRock reserves contain considerable amount of recoverable Ilmenite. The majority of ilmenite is used in the production of TiO2 pigment (paints, coatings, plastics, ceramics) for which there is a global market and for which Quebec is a currently major supplier. Ilmenite is also used to produce titanium metals for use in many applications from aerospace, automotive, medical and sports equipment.
BlackRock has conducted significant metallurgical tests carried out at laboratories in Quebec, Ontario and Australia which demonstrate that the BlackRock ilmenite concentrate compares very favourably with other TiO2 feedstock sources because of its low calcium and magnesium content and due to a very high ratio of reactive FeO to Fe2O3 iron.
This means that the BlackRock ilmenite is quite unique and suitable as an input for either Chloride or Sulphate route downstream processes. If fed to a slag process, the BlackRock material has been demonstrated to produce a high Ti product at or exceeding many top producer’s specifications.
Commercial titanium slag is an intermediate product used as a feedstock to produce titanium white pigment and other products. Initially considered a waste product by the project engineers, the BlackRock team has been successful to refine the manufacturing process so as to expect commercial titanium slag production from the start of operations thereby reducing solid waste at the second transformation site to almost zero.
