Answer: Zinc is more suitable for reducing the leached copper ore.
Explanation: At a site, low grades of copper is present and we need to reduce it by using zinc or iron. So, the copper is best reduced by zinc because it is more reactive than copper and hence, will easily reduce it.
Reactivity of metals is determined by using the reactivity table of metals. The metals which lie above in the series will easily reduce the metals which lie below it.
Reactivity able is attached below.
Hence, Zinc is more suitable for reducing the leached copper ore.
