Park City. yil j ' :' 1 n logical keeping with the era of V t ; great expansion both as to extent of I '( territory niid extent of future possibili- ' j LI- tios, the management of (he Silver Kinp I jjj ' Coalition Minos conip.niy.has been bus- l j ily enpaped for some time past in en- rf, Jarpinp and addinp to the various ac- ' I r j cessories to the mine and equipment. I ' One cannot see the numerous under- '' I L t i und workings wiiich go from tlie old ' " j ' I Silver King 'to' the nowly ncquired pos- j - sessions of this company, oonncctions 4 I; ' already having been made in several in- stances, but what ho can appreciate is it the, change that is being made in the II , concentrating plant upon the property. ' ; i , They are necessary and important. , i The present capacilv of the plant is i j . t0, ,no practically doubled by the nd- j dition of the equipment now' being set 'A ' I nlace. This means that the plant 1 p ! . shortly will be handling in the vicinitv It' of 500 tons of ore per day, a capacity 8 h I that in a short time may p'rovc too lini- l i j itcd for the mnnner in "which tho tcrri- ill ' , lory within the lines of the company 4? , . will open up. Starting ni the point I M where the ore first roaches thn mill. H'jl , I' tho rock crushers there, is evidence of f) I 1 ihe first addition to the plant. The V, V ! comnaii3- at present is operating two J small frushers. but a larger one. capable W f of handling thirtv t.ms of rock per i , T . hour, known as the Comet, style "D," ! t l,as llcon received at the mine, and will . ' ? , be installed closer to the scales than "f ' 'i the other two. '( i New Section Being Added. Bi 1 i ,1 From tho storage bins to the crush- .'! 1 prs' aml from tno latter to tho bins , i ;( above the feeders, the companv is in- V, i j i I: Hailing a svstom of belt conveyors H , a j. i' which will be a decided improvement H' ! ' '' over the present conditions, in the mill H. ' I A is being "placed into shape a complete 1 j! sow section. This equipment consists H, , 1 1 (i ( of two new sets of rolls, a complete :i et f the Trommel revolving screens. n , r ' another complete set of jigs, making, S I ! when complete, an equipment of twen- Jt' ' (! , ty-four two-compartment Hart 7. iigs. Hlij ' ' , This equipment in part has come from 1 jl . : the mill of the former lvearns-Keith V i companj-, now merged into the Coalition ' I organization. Tho Silver King mill was i i j j Bufncientl.y large to enable this ma- H 1 f - ' chinery to he installed without increas- H;7i( QC the roof space. H' iT I vP'' 0 neTV' (lewateri2ing wheels are H'i f ' 'i being installed, and in sueh a manner ' '.: ! : that either wheel can be operated from , 'i I; either section, or both together, so that i . , in case repairs are necessary to either H ( I section the mil) can bo kept running, Hn in part at least, without interruption. Hji i A The superintendent points out that the I , Silver King mill seldom loses a min- I i nte during tho day, a ten-minute loss H' in twenty-four hours being the extreme H; j1 case. Of the Tfilfley tables and fruc W- ij , vanners, the company at present hns H,' A twenty-one, and to these eight, more are K '! being added. There has just boon in- Ht 'j , ''j i stalled for a sufficient time to demon- B'( "' otiaio its merits ono duplex Callow Rjjj i, 'im screen, which sizes tho pulp from tho H ii, Huntingtons. To this will he added 'f If ' a.nother at once. For the purpose of BJ f drying the concentrates, the company I. 1 1 .". adding a new flat steel dryer wjth a B" t liX 1 K Burface area of 1200 squaro feet. This i lH t drj'er will be operated by the exhaust H i k?. steam from the mill, and it will be B'iil u constructed along the lines shown do- Hs( r h i I Arable b- the experimental dryer now v. 'ns new section will be provided H. f,j jlv J with power from two new S0-horse- j U) 6 power return tubular boilers, for which B ' v !' I a building is being erected. This build- B II V 'l inP '? beinxr made sufliciently largo to HinK '! I combine boiler room with a storeroom J , ' H j1 22 by 24 feet. The foundations for B 'ij ' If' tuo "oilers ii"1 already completed, and j, M ; installation of the equipment should B'- " 1 follow soon. The mill is kept in opera- H ', I ' tion without let-up pending the installn- v ' tion of the new section. A new blnck- B ' M'. emith shop and pipe and iron storage B"' 'I Toom have been constructed adjoining Bt ' !il ne an'l where the new tables arc B ; to rest are being sol up seventeen eight 1 ii'f i ioot Callow tanks. It is stated that, the ,'i lEuving of water from tho new eomp'art- B ' 'r il men l will equal the operating expenses B J jl 1 1 L lof samc B 'j V? : Iuterostiug Slime Department. B ' '!; ji' ! One of the most, interesting features BH II ' 'lver King mill is the slime Bj I l'1 department, a purt of the plant that j ' 1 i 'TviU bear another mention in these col- B r '' ' mnns. This department handles the fine B i j j , undersized particles that ponotratc a H ' i ' 150 mesh from the jig floor. By no HV j ii ordinary means of metallic saving could B( j 5 c'vc'r Per ccnt the values B ' I contained bo saved. This product is B i ' ' 1 ;fhrown into a system of settling tanks, . j , where the water is settled to a clear j j ', overflow. The thickened pulp is then B 1 I ' i I . Pt into receivers and air turned on at B ' 1 i l n Pr('tsi,rc f pounds, forcing the B ' ( i'i m"r through a filter press, where the B ' il s0'i'' part icles lodge. These particles H''j n are then taken out in the form of fir- B U t cuiar cakes one and a quarter inches Bl i i thick and forty-six inches in diameter, Bf ! an lried upon a flat steam dryer, from H. I i which point they arc ready for mnr-ij mnr-ij ket. This process make a product in B'f' 1 I lead, silver and gold worth $20 to $30 B' '' ii Per ton, and at a cost of $1 per ton of Bj 4 I completed product. This particular dc- B i partmeut of the mill is unusually in- B 1 Jj foresting. ' I 1) As to the saving in the mill, without Bl r 1 I 1 giving the figures, it can be taken for : j ! !, granted that the standard of efficiency B i 1 ' h -B very I'-J?'1- '8 noticeable that no B 1 1 1 'il I persons seek to make a living by skim- B; y ming off the tailings creek below the B ' til- mill. And when the completed addi- Vf i' tiong are ready for work, it is safe to . 6a.V 'iat there aro few mills anywhere that will bo doing better work in the B i -tank of saving metallic values from B ! i milling ores. H j ( I j, what, impresses every visitor to the ; ft Silver King is the absence of dirt, dis-' dis-' order and debris. The mine and mill H- : arc kept neat, and clean, while the Bj 'I premiseH generally are absolutely free r I from unsightly accumulations ao usual j about mines. |
