Later, tin was found in the Iberian Peninsula, and it was possible to produce a copper–tin alloy (bronze), which was used in the manufacture of tools, implements, weapons, andAn analysis of operating plant issues and the minimization,,likely variations in feed to the processing plant and the approach to the design of the plant and its operating philosophy.
