Breaking – Minecraft Wiki
Breaking, digging, punching, or mining is a common activity in Minecraft, performed (by default) by holding the left mouse button or right trigger while the cursor is pointing at a block, or by long-pressing on the block on touch screens. Breaking is the primary way to remove unwanted blocks and acquiring blocks for future placement or crafting.

Rock-to-Metal Ratio: A Foundational Metric for …
The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for …
