摘要: Technological advancements dictate the productivity growth in all industries, including extractive ones. In peculiar case of metallic mineral this is also impacted by natural variation metal content and chemical composition ore input, course cumulative extraction depletion resources. Through a disaggregated treatment data achieved using input-output on subprocesses copper production correlating them with input characteristics (ore grade), study identifies evaluates impacts periodic changes as well those technological progress, while reasonably controlling influence other unrelated factors. This provides an objective assessment manner extent mitigation impact depletion-driven inputs said industry, through advancements. It reveals that continuous incremental developments technology, successfully offset detrimental effects sector productivity, often aided geological changed to miners’ advantage. However, stands outweigh gains from innovative technologies, soon ores breach minimum threshold level purity or chemistry. thus establishes usefulness studies estimating may not proceed strictly sequential uni-directional manner. More importantly, it shows are neither uniform nor linear always growth. Though primarily based findings hold relevance for industries too.
