ORE FLOWSHEET16 Nov 2023 23:26
After the bombshell with Horizonte, I had a quick look at their flowsheet. Their basic ore is a laterite. understand the crushing, screening and drying of the ore. I find it most unusual that the ore is not concentrated prior to going to the furnace.
The ore cannot be predominantly nickel. I would have expected some magnetic separation and then jigging or other gravity concentration to upgrade the ore prior to the furnace which is a very costly exercise.
I would expect the company that had the contract to design the plant and do the DFS to be hauled over the coals. Plus Horizonte management should be 100% to blame if this is the case.
