One good rule is to get your crusher as reasonably high as possible, as it is cheaper to pump your feed water a few feet higher so as to get a good clear run for your tailings, and also to give you room to erect secondary treatment appliances, such as concentrators and amalgamators below your copper plates and blanket strakes.
Of pan concentrators there is an enormous selection, the principle in most being similar i.e., a revolving muller, which triturates the sand, so freeing the tiny golden particles and admitting of their contact with the mercury. The mistake with respect to most of these machines is the attempt to grind and amalgamate in one operation.
And our own San Francisco has its Hibernia and other banks of its kind, with from $5,000,000 to $30,000,000 of capital. And when it is remembered that the total deposits of an individual in most of those institutions is not allowed to exceed $3,000, we can see that the people will not fail us as "concentrators" when their help is needed.
In the solution of this puzzling question which was finally reached, the great mirrors and burning glasses of the Solaris concentrators, were again called upon to play an important part. "The first necessity, was to reduce the weight of the vegetables, and at the same time, to arrest all tendency to decay.
The mode of extraction longest in vogue, and after all the cheapest and most effective, for free milling ores where the gold is not too fine, is amalgamation with mercury, which metal has a strong affinity for gold, silver, and copper. As to crushing appliances, I shall not say much. "Their name is legion for they are many," and the same may be said of concentrators.
Fine concentrators, worked with cyanide solution, perform three operations at once, namely, first, the catching of the free gold grains; second, the production of a rich concentrate of minerals having gold in association and intended for smelting; and, third, the dissolving of the finest particles by the continual action of the chemical.
I watched the "concentrators" at work big tanks containing mud and water and invisible diamonds and was told that each could stir and churn and properly treat 300 car-loads of mud per day 1,600 pounds to the car-load and reduce it to 3 car-loads of slush. I saw the 3 carloads of slush taken to the "pulsators" and there reduced to a quarter of a load of nice clean dark-colored sand.
This typical mining town does not pretend to have any sacred days or sacred hours. Business, money-making and sporting are the great aim of life. The mines work seven days each week and twenty-four hours each day. The great concentrators know no pause; the cables are ever busy transporting the mineral from the tunnels to the mills.
There was darkness in the mill, but when they brought the flares, Wiley saw that the ruin was complete. From the rock breaker to the concentrators there was nothing but splintered wood, twisted iron and upturned tanks; and the demon of destruction which had raged down through its length was nothing but the fly-wheel of the rock crusher.
He has cultivated that rarest of arts which is to be a good listener. He is one of the great concentrators. In this genius, for it is little less, lies one of the secrets of his success. During a lull in legislative proceedings he has a habit of taking a solitary walk out in the lobby.
