It appeared he had "served his time" in the copper-ore trade, the famous copper-ore trade of old days between Swansea and the Chilian coast, coal out and ore in, deep-loaded both ways, as if in wanton defiance of the great Cape Horn seas a work, this, for staunch ships, and a great school of staunchness for West- Country seamen.
I went over these works, and gave particular attention to the refinery. Some of the processes for collecting the metal are ingeniously simple and effective. The copper-ore is remarkably pure, being, it is said, free from arsenic and antimony. The concern ought to pay, for the copper is so well esteemed that it obtains the best price in the market.
Thus we discovered that the smelting of copper by electricity, and of reducing it with metallic iron, would not pay. Our statistics are short, but they are heavy: about 300,000 tons of copper-ore are annually smelted at Swansea; 28,000 tons of copper are annually produced; and 600,000 tons of coal are annually burned.
Having previously made up their minds what to offer for there is nothing like a saleroom competition the smelters hand up a folded slip to the chairman, who announces the highest offer and the purchaser's name. With such expedition does this proceed, that different cargoes of copper-ore, to the value perhaps of L.50,000, will often be quietly disposed of in a single hour!
He had had too much experience of Departures and Landfalls! And had he not "served his time" in the famous copper-ore trade out of the Bristol Channel, the work of the staunchest ships afloat, and the school of staunch seamen?
The cargoes are usually consigned to a particular class of brokers, indigenous to Swansea, and known as 'copper-ore agents. The ore is by them deposited in large yards, where it is crushed to a certain fineness, for the purpose of obtaining a proper admixture of the 'heap. Notice is then given to the different smelting-houses, who procure samples of the lot, and assay it.
In several spots of the valley of Caracas, the gneiss contains a small quantity of gold, disseminated in small veins of quartz, sulphuretted silver, azure copper-ore, and galena; but it is doubtful whether these different metalliferous substances are not too poor to encourage any attempt at working them.
At Jajuel I was informed that the copper-ore, with some gold, is found only in the greenstones and altered feldspathic clay-slate, which alternate with the purple porphyritic conglomerate.
