March 3, 1877.] MINING AND SCIENTIFIC PRESS 14) {Copyrighted. ] Mechanica! Ore Concentration and Separation—No. 24. {Written forthe Paxas by Fraxcis M. F. Cazix, ME, Santa Fe, New Mexico. . I have thus designated all that should be gathered for treatment in the shape of slimes in all mineral dressing establishments, and this collection should invariably be effected, whether further mechanical separation or direct reduction be subsequently applied. It is here befitting to describe the mode of collecting slimes out of water. They may be collected and passed into further treatment as pulp, or the yep may be allowed to dry, as it readily does in dry chmates within a very short space of time, without the help of fire and heat. In case 0} , direct reduction by roasting, otc., the dry and solid pulp requires a squeezing, affected. beat by piles, Voven hard wooden ones are adaptable,) in order to recover the state of powder or dust. Introductory to the description of the collecting apparatus, 1 must draw the reader's attention to a material modification of action, the result of practice, which takes place in treating slimes, from what is invariably maintained in treating the coarser sizes. Coarser sizes, without any exception whatever, are firat thoroughly classified by size and then separated by quality. For finer sizes (slimes) this course would be also correct if it were feasible to the same full extent; but screens will not classify below a certain size, say one-third of a millimeter, and therefore other means of classitivation must be resorted to. These means are the exposure of the particles to the effect of a horizontal water stream. Such streams can be made to classify material of equal specific gravity to perfection. Thus quartz particles ao classitied may be collected in lots of perfectly equal sizes, but if amongst the ee of quartz there are heavier particles, ‘or instance of galena, then smaller particles of galena will be gathered with larger particles of quartz (one-eightieth inch particle of galena will gather with one-twentieth inch particle of quartz, and other sizes in the same proportion). Such particles of different material, which will simultaneously fall or be kept in suspense or be deposited in an upward vertical stream of water, are called ‘‘ equal falling,” and the action being ‘certainly in part, and evidently the predominant part, that of classificati is idered in practice as such. Thus the difference is constituted between 1 1, Classitication by screens, and 2. Classification by streams of liquid (or air). The collecting apparatus now to be described is also and at the same time a classifier of the second class, The subsequent action of separation varies according to the previous mode of classification. In Number 10 of this series, alluded to before, we have stated the principles on which separation is based when classification of the first mode is applied, and hereafter we also will find the proper place to state the mode of operation for separating material classified by the second mode. General News Items. Dr. Tempe, pioneer of homeopathy, and founder of the Homeopathic College, Missouri, died last week, aged 70. A Mabe special announces that the Spanish Minister of Foreign Affairs is sel upon a draft of a treaty of commerce with the United States, Hxsrer, Tully and and McHugh, the Molly Maguires on trial at Bloomsburg for the murder of Alexander Rae, near Centralia, Penn., have been found guilty. Tue printers of San Francisco are making arrangements for a picnic to be given at Damon’s Grove, Saucelito, on April 15th, in aid of the cemetery fund, , SECRETARY RoBeEson says if the proposed reductioa is made in the appropriation for the pay of officers and men of the Navy serving abroad, the ships and crews will have to be brought home at once, Tue probability is that Rear-Admiral John Rodgers, now in command of Mare Island Navy Yard, will be ordered to the command of the Naval Observatory at Washington, in place of Rear-Admiral Davis, deceased. Sainas Crry, Monterey county, has a sensation; a defaleation of $20,000 having been discovered in a county official’s office. The court house was burned a short time since, and it is believed that the records were burned to destroy proof of the defalcation. Peririons are being circulated throughout this city calling upon the Board of Supervisors to raise the license fee of liquor saloons, in the belief that the low dens and dives which abound in certain districts will thereby be compelled to give up business, A Beverabde dispatch says: All day Saturday and Sunday wagon trains have been transporting a large quantity of small and large ammunition from the fortress of Belgrade to the quay, to be taken down the Danube this morning. This movement contrasts with the peaceful news from Constantinople. ‘Woopwarnp's GARDENS embraces anAquarium, Museum, Art Gallery, Conseryatories, Tropical Houses, Menagerie, Seal Ponds and Skating Rink.
