What happened?

In this modpack you can double almost every raw metal by using an ore hammer to crush it into two metal dust. However, this is not implemented for ores added by Modern Industrialization i.e. Antimony, Tungsten and Titanium. This seems rather arbitrary than intentional.
EDIT: This is also the case for Crimson Iron and Azure Silver (added by Silent Gear)

Some additional thoughts:
There are already dust variants for the mentioned five metals so only the recipes would need to be implemented. However, tungsten and titanium are currently not supposed to be smeltable in a regular furnace but rather require advanced processing, and they would need special consideration to keep this behavior.
