The Circored Iron Ore Reduction Plant in Trinidad

I uploaded the case and Chapter 3 PowerPoint which are the only materials that the writer needs to use. Moreover, please follow the instruction below:
Introduction:
This case is written with a primary focus on operations strategy and /or quantitative methods. The question of this case is straightforward - Shall we close down and write the plant off? To begin the analysis, we need to understand the process flows. Chapter 3 in the textbook provides a relatively detailed structure of the process flows. Following the process flow analysis, the operation's cost structure is required to be conducted in order to make a recommendation.
The alternatives could be:
Discontinue the operation immediately.
Move the plant to an idle status.
If the plant is not to be closed, consider additional investments to fine-tune the process technology.
Based on the information above, please answer the QUESTION - As a member of, or a consultant to, the board of Cleveland Cliffs, what would you recommend concerning the future of the plant? Discuss the alternatives, then reflect what this means for Cleveland Cliffs' long-term valuation. (this is the key part of this order)
