1 (a) A student is provided with samples of six metal carbonate ores, known to be ores of the metals barium, calcium, copper, iron, lead and zinc. All the ores contain carbonate ions and some might also contain hydroxide ions. Each ore sample is ground up and a measured mass of the ore is reacted with an excess of dilute hydrochloric acid.

The copper metal in the ore was reacted with excess nitric acid and the copper (II) nitrate produced was reacted with excess sodium carbonate. The mass of the original ore sample was 3.507 g and the mass percentage of copper in the ore was 34.6 %. How many grams of copper (II) carbonate were produced? Assume 100 % recovery in each reaction step.

The isotopic 'fingerprint'—independent of the chemical 'fingerprint'—is based on the ratios of the various isotopes of lead present as an impurity in copper ores (Rohl & Needham Reference Rohl and Needham 1998). The materials analysed chemically and for lead isotopes were: • Copper ore samples from throughout the Bronze Age workings.

Firstly, the copper ore samples were cleaned to avoid the dirt on the ore affecting the final result of the spectral experiment. Then the samples were dried to remove the moisture in the ore so that the spectral experiment could reduce the interference as much as possible. Finally, the samples were ground into powder to facilitate spectral ...

In the example in figure 25 the weight of the bead is 0.017 mg, which is equal to the ounces of gold per ton of ore, if an assay ton, 29.167 grams of ore, is assayed. The gold weight, 0.017 mg, and the silver added, 2.00 mg, is subtracted from the dore weight, 2.17 mg. The difference, 0.15 mg, is equal to the ounces of silver per ton of ore.
