The Minnie AND Sorentart0 Pris enters up. on its 28th volume at an important period i in the history of onr Coast. The mining interests have never been more prosperons than during 1873; nor have we ever had a brighter ontlook _ than is hefore ns for the New Year. The diy“idenda from. mining incorporations on the lists of the Boards for 1873, have amonnted to the eum of $13,356,000, as compared with $6,731, 100 in 1872. The. large profits from nomberless other mines not known to Stock. Brokers, swell these figurea immensely, and 1874 is expected to eclipse its ‘Predecessor. . " , . The number of persons engaged in i mining is increasing, and our subsoripfion ‘iat inoréasés also, as we'represent that class of people. We shall stillcontinne to gather information from all reliable.sonrees, such as will he interesting tor our readers, and:endeavor to make onr “paper! ag’ ipractiéally nseful to the mining comuinnity j as ‘possible, All the new and improved prooess-. es for the rednction and. amalgamation.of ores receive special attention, We maintain the most comprehensive review of the mines of the Coast in our weekly mining summary that it is possible to procnre, whioh in itselfis worth more than the price of the paper.

Antimony Reduction. ) / “ Althongh ‘sntimony ores have been fonnd in several places in Nevada and’ the reduction ef this metal has been tried af, different times in that State and in this city, it hag not seemed to have heen carried on ‘successfnlly; at all events operstions have been discontinned. The nse of antimony is very extensive;: ita principal. value being’ as an alloy with tin, lesd, oopper or bis-. muth for shaft hoxes, type, queeu’s metal, eto., and also in combination with, oxygen, sulphur and other snhstsnces as medicines, of which there sre some ten or ou Cua jeden: tions. The principal ore is gray antimony 0 or snlphuret of antimony, which occurs so often in yeins with silver ores in Nevada, Idaho, é6tc. This ore yields nearly all the antimony of commerce. The mineral sometimes contains $150 . perton in silyer. The white antimony and antimonial blende occur less ‘frequently. . The assays of sulphuret of ‘antimony, if made hy . fire, are: not reliable nnless melted ata ion ‘\hest, and prepared . in the “following _ way: Five parts of. : antimony ore are mixed with ten parts of prnssiste of potsssa and covered with two and a half parts of oyanide of potassinm. This method of assaying, if the ore is melted at a cherry red heat, gives 72 per cent, of the antimony; while all the other ways. give less. i There are two processes of redncing antimony ores, eith— er by the procesa of liqnefaction or, by direct’ smelting for metallio antimony. The liquefaction is . Wie ticable with, sulphnreted ores. It , jaa separation of the snlphnrets from the gangue by heat, and yields crude antimony, which is. . nsedforseveralteoh©." nical purposes, bat principally to make metalio -antimony. This process has in aoma ‘places the ad-. vantage that no finx’ easily Performed tear the mine, especially where there is no water, to-ehable, them to concentrate. ‘ The process of liqnefaotion always involves a loss of from'10 to 12 per cent.in antimony, but it is’ “nevertheless practiced i in many places “This process is carried on éither in earthen pots, or-eruciblea ‘or iu liqnation furnaces similar to roasting furnaces. In some parts of Gerthany and Hungary earthen pots are in use (especially for the richer ores) similar in shapeto:the French assay crucibles, exoept that the lower part is somewhat: extended so as to fitin another pothelow. The hottom of the crucible is perforated and the lower pot is snrrouuded hy ashes. It reqnires alow heat to melt the antimony, which flows into the pot helow the crucible. In other instances the Pots are placed iu fnrnaces of very different oonstruction, hnt always so that a number of the pots, from 12 to 15, are placed in a circle so that one fire may heat them all. The most practical fnrnace of this kind for t a larger prodnotion, is that ‘used in France, an engraving of which is ahown on this page in vertical sections. The fnrnacé has ‘three fire places, e, f, g, tho'prates being 4 féet 5 inches long, hy 10% inches wide.

Last week, of the Utah mines, the Emma shipped 70. tons, Flagstaff 100 tons, and Grizzly 130 tons from Little Cottonwood.
