Block of the Week: Copper Ore | Minecraft
Unlike other ores, like iron, the block itself won't drop when you mine it (unless you're using a silk touch pick). Instead, you'll get a few chunks of raw copper, each of which can be smelted into a copper ingot. That's nice, because you get a little more copper per ore block you find than you would with iron.

The copper mines at Middleton Tyas are better documented in the eighteenth century but deserve an article of their own. In 1862 copper ore was discovered at Merrybent and a mine opened in February 1862. The ore cost 19s per ton to raise, and sold at £6 15s 8d per ton. It was sent to Birkenhead for smelting by rail from Catterick Bridge Station.

Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Under-grinding reduces recovery; overgrinding reduces throughput and wastes energy.
