Copper extraction

However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included hand-sorting and gravity concentration. They resulted in high losses of copper.

Iodometric Determination of Copper

Iodometric Determination of Copper.pdf. If excess ammonia is added, copper(II) hydroxide redissolves, forming the deep blue copper(II) ammonia complex, Cu(NH). If the excess of ammonia is large, a large quantity of ammonium acetate will be produced later; this may keep the reaction between copper(II) and iodide ions from being complete.
