Glencore chief executive Gary Nagle said investors are not pushing for his Australian-dominated coal business to be separated from Glencore’s critical minerals mines, despite such a split being a central part of his $US23 billion ($43 billion) plan to merge with Canadian miner Teck Resources.

Teck formally rejected Glencore’s plan to execute the biggest mining deal in a decade by merging the two companies into “GlenTeck” on Tuesday.
