Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

Abstract. We will never know who first smelted copper. Nevertheless, archaeometallurgy has made considerable progress in identifying where, when and how our first industrial metal was made into tools. Stone tools had served us well; however, copper proved to be more versatile especially when combined with tin to make bronze.

The head assay of a copper ore is 0.8% Cu. The expected overall copper recovery from the ore is 88%. Calculate the maximum stripping ratio if the total cost of production (excluding overburden removal) is $5.90 per ton of ore and overburden removal costs are $0.3 per ton of waste. Assume copper values of $1.00, $1.25, and $1.50 per kg of

Copper holds the balancing forces of the warmth of the sun and the calmness of the cool moon, which translates into a similar kind of balance within you when you meditate with it. The stone has an excellent ability to give you the confidence to express yourself more openly and effectively and admit to your true inner self.

The ore as mined was not pure as it was mostly encased in rock, combined with earth, and also contained traces of iron ore and other minerals. Firstly it had to be pounded into small fragments on stone tables with rock hammers, then ground to a fine powder of 1-mm grain size in a stone mill (very hard work!).

A Millstone can be powered by a shaft from below or by a cogwheel from the side. There are two ways to insert items into a Millstone: Dropping items on top of it: anything that can be processed will be picked up if the input buffer is empty. Hoppers, Funnels

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Some masses of copper occur that are too large to handle and must be cut by cold chisels, a method that costs more for labor than the value of the metal.

Abstract. Around four hundreds prehistoric copper tools and weapons have been recorded in the territory of Serbia so far. They had been in use for a rather long period of time - from the end of the early phase of the Vinča culture until the Middle Bronze Age and some types of these objects even until the very beginning of the Iron Age.

A metal is leached from an ore or concentrate with an aqueous solution of an organic chelating agent. In selecting a suitable agent the formula Beta >10 3/Ksp is employed wherein Beta is the stability constant of the chelate composed of the agent and the metal to be leached, and Ksp is the solubility product constant, in water, of the compound in the ore or concentrate which supplies the metal
