140 SCIENTIFIC PRESS) {March 2, 1872. Wastage of the Precious Metals—No. 3. BY ALMARIN B. PAUL, [Written for the Press.] Montana. “The trouhls sssms to hs the gold is so impalpshly fins that they loss a very considsrable percentage by imperfect manipulations,” says ons. “T hsvs nsver saved more thsn $20 per ton and the ors assays about $50,” says another. Extend tests as far s8s you may, on a smaller. or larger scale, and wastags stsres ons hadly in the face at every turn, I mads a tsst of 50 pounds of tailings for a party who took them a mile above his mill aud the rsturn was 55 per cent, of what was his average workirg. I also msdea test of three-fourths of a ton, and the result showed ths loss in ths mill-working to he 63 psrcent. Icould write every column of your paper full, corrohorative of ths fact of the enormous loss in the milling of our gold ores. But these given should be as convincing as more; and I hope enough so, to awaken a desire for investigation at least. From what attention I have givsn the subjsct in actual lahor, as well as collecting all the data attainable from others, I know that the loss as a whole is fully 50 per cent., and, in the majority of mills, all of 60 per cent, of what the ore contains. I can now ask: Is it not time we were heginning to consider this question of the wastage of the precious metals? It is this that produces so many failures, such utter lost of capital. Investments are made in mining on assays of well sampled ores of the mines, hut not until machinery is running, do they realize the fact that only a small percentage of the metal is saved, and a failure too often is inevitable, Among the evils of mining may be enumerated, at times, toomuch science and too little practice;then again conceited practice and no scisnes. Science is esssntial, practice equally so; strictly, scientific mining may be denomiuated, science doing nothing; practical mining, science doing something; practical-scientific mining—the grand requisite—is a correct conception of cause and effect—the scientific analyzation of difficulties and the practically overcoming them. But to my subject, There are a numher of institutions in California that have proved grand successes. They have been exceedingly fortunate, hut their success may he attributed to having ores of high value, not to gaining a high percentage of the metal, For take California mills, and the first class are all on a par in wastefulness, while the poor are not to he considered at all. My tests are from the best, and JI leave the reader to fancy what the poorer ones may be. California in twenty-one years has produced over $800,000,000, and wasted $1,000,000,000 more !! Forthe wastage in ‘“‘sluicing” is greater than that in quartz mining. The Sacramento river in ages to come, and when it shall he upheaved as were the Sierra Nevada, will gladden the heart of some straggling miner with an auriferofs stratum, the wealth of which will throw all histories of-Potosi’s, Comstock’s, and Del Rey’s comhined, into the shade. To remedy the evil, more care must hs taken, The fact is, we are too much of a rushing, reckless people; we have not got sohered down yet; and I dont know as we ever will. It’s rush, rush, and make too little solid, permanent, profitable headwsy. We have oceans of wealth surrounding us, and ought to be ths most opulent, refined and wealthy land on earth,—the load-stone for God's creation. But how is it, and why is it, that we are not? ‘When one examines into the mining interssts of the world and analyzes gold, its fineness asa metal, and then the science which has maintained the general system in vogue for gold more especially, and see how many, many years, all have gone along with one so reckless and wasteful he almost hlushes for the science and mechanical skill of the day, for a greater absurdity cannot exist than the rough, coarse way of dealing with so delicate ‘and valuahle a metal as gold; the general treatment hsing not to catch it hut to run it off. It seems to me, men go mors on what somehody else has done than their own analytical powers. From data of loss, given in my last article, we must come to the conclusiou that gold mining, not only in California, but elsewhere on the Pacific slope, as all are operating on about the same system, is unquestionably behiud all other hranches of industry in perfectness, and certainly not up to the point it should be, In fact, so imperfect is it, that our gold mining enterprises, as a whole, may be set down as a failure, when ths question of profit in all is considered, Jf ib can he considered highly successful in this gsnsral sense, ought we not now to hs teeming with prosperity? That soms chsngs should bs brought ahout, must hs evident to all. What that changs will bs or should he, each must determine for himself. In ordsr to better ths interest, all operators should give their attention to incressing the percsntags of yisld without a correspondiug increass of expenditurs. hers is a hensfit, however, in producing mors,evsn with an equal sxpenditurs, ag it gives an additional amount of metal for circulstion, and requires an equivalent of lahor. But this idea, although correct, is an ‘anpopulsr one; it does not helong to ths selfish spirit of the ags, for without a profit on lahor, it is not wanted. This agsis for profit, not good, unless the ‘“‘ good” makes the profit. Ons step in advance would hs,—taking more care. There is too much slashing ahout in our gold mining. Thers is snough in silver, but no comparison hstwesn the working of the two metals. This plan of seeing how much can hs pounded up and rushed through every 24 hours, is a false, wasteful and ruinous system, The profit will he found in how well and how cheap it can be done. Itisin the right direction certainly to reduce ores expeditiously and cheaply, but not to as expeditiously wash everything away, having an eye more to pounding up the rock, than to taking up the metal. The following slip, clipped from the Press, to my mind, tells quite a long story in itself: ‘‘Here is a40-stamp mill, that pulverizes its 250 tons weekly, employing 40 to100 men. The ledge averages five feet thick. The Montezuma, too, is located here; hut for reasons hest known tothe company, they have permitted their 20 stamps and a good mine to remain idle for the last two years.” Forty to a hundred men gutting a mine, torun how much down stream? I know ssveral similar institutions which work from ‘‘40 to 100 men,” and at the end of the month the owners do not have one dollar for themselves; whereas Isss expense, less rush, and more metal saved, could turn the scale often from loss to profit, and ‘‘20-stamp mills with good mines” need not he idle, I contend that ore can he reduced, held under control for manipulation, and metal amalgaiaated as cheaply as this uncontrollable sluicing system so universal in California. That our gold oresare soreadily amalgamated, is one of the ruinous ideas extent, The majority of California miners are, in fact, hut little experienced in all the troublesome accompaniments of even gold ores, considering that if the rock does not pay, that it cannot certainly contain it. All, however, admit it to be difficult to extract the gold from iron sulphursts, forgetting that evena small percentage of lead, copper, arsenic or antimony which isto he found in nearly all the gold ores of California, vitiates the mercury in a little while, rendering it quite inefficient in collecting even the gold that otherwise from gravity might betaken up. We hear great accounts of ths value of ores from all parts; hut do they prove up their asssrtions hy the product per ton? One of your correspondents, only a week or so ago, stated in his communications that ‘we must have improved machinery or abandon this in use.’ He had heen investigating the matter, It is too universalto consider that it is only necessary to rig up a set of stamps, apply the power, and let them rip away smashing rocks, to wash the sands off, forgetting that it is equally as patent to wash off the smaller particles of gold.
