Making outline
- Decompose selected clean scheelite concentrate with aqueous hydrochloric acid in heated vessel, separate hydrated tungsten oxide residue and wash
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Distinct isolated intermediate; retaining purification before carbide use."
