Refractory-or complex-are terms given by smelters to ores containing two or more clements requiring a special treatment to recover the values.
 Such ores are either refused entirely by smelters or the refractory elements are penaliZed so heavily that the values are partly or entirely lost to the miner.
 Mining men feel convinced that pen alizing ores in many cases is only one way in which smelters collect unfair tolls-for in these days of metallur- gical science-there is no excuse for losing metallic values of any impor- tance
 Western smelters do not handle tungsten, antimony, molybdenum or other rare minerals-and but few are in the market for zinc ores. Such ores must be shipped to eastern smelters that are especially equipped to handle them. There are no reliable quotations of values published, or dependable mar kets for rare or complex ores. On the contrary buyers at present require owners or producers to fix prices, ex- cept where a buyer is anxious to secure the ores.
 The ores of Arizona, are, to a very 1 large extent, refractory or complex.
 The most perpleXing problem that has confronted mine owners was, and is yet, to recover the values from the ores. Those who were unable to equip their mines with suitable machinery have been forced to ship to smelters and submit to heavy losses through unfair deductions for moisture" and penalties. Also discrepancies between local and shelter assays. Hundreds of such cases could be cited
 Shelters are not alone to blame The scores of idle or dismantled mills rep resent millions of dollars spent in legitimate development work but with i out a proper knowledge of how to treat the ores. It is because of such unfor- tunate conditions and circumstances, that the great mineral wealth of the Aountry is so slowly develop ped-but it hnly requires a readjustment of the | conditions to reverse the whole propo- stion.
 A mine that has not proven a suc- cess-no matter from what cause-is ! branded failure.
 Fortunately the most of these mines and hundreds of prospects" upon which fortunes have been spent will have a chance to prove their value. ! They are rich in gold, silver. copper and lead and most of the valuable rare minerals such as tungsten, molybden- ! um, etc, also zinc, antimony and other refractory but valuable metals, worth millions.
 i These ores are now to be treated, { when possible to do so, at the mines to save wagon haul and freight charges, by the most scientific and modern processes that will save practically all of the value and largely upon a profit sharing basis.
 A mine owner and operator, now a citizen of Phoenix, has had 25 years experience in California, Nevada, Utah and Arizona, and now largely interest ed in mines tributary to Phoenix has solved the mining problem.
