Increased Copper Recovery
's described in (hapter )* the addition of +a(l prior to the agglo$eration stage allows allo ws for an increase in the $etallurgical recovery of copper in sulphide $inerals. The projected increase fro$ ,- /for $i&ed $inerals loaded on the o&ide pad0 and ,1 /for sulphides loaded on the sulphide pad0 to a projected 21 of (u cathode produced corresponds to an 2 to 31 increase. This increase in $etallurgical recovery* together with other factors* would contribute to a change fro$ the Lo' 4BP -135 $ining plan to the Lo' 4BP -1356FS $ining plan* which consider an increase in copper production fro$ 215 to 27, 8t per year over the ne&t five years* through the e&pansion of e&isting processes or the introduction of new technologies. Reduced Water Consumption
Sulphides are currently treated by bacterial leaching* resulting in an upper li$it for chloride concentrati conce ntrations ons /9 g:L (l !0 in the sulphide plant solutions. ' portion of the sulphide raffinate is purged into the PLS o&ides pond* resulting in a volu$etric i$balance in the o&ides plant.

"$ple$entation of the Full SaL SaL project will will allow for the eli$ination of the purging step* reducing the water consu$ption fro$ 1.-9 to 1.-1 $ 9 per ton of treated ore. This will help to reduce operating costs* as well as leaving water available for alternative uses. Increased Process Stability

The operational philosophy for the $ine will re$ain as it is currently* but releasing the $ine type restriction. 'ccording to the Full SaL project operational sche$e* there will be no o&ide or sulphide ca$paigns* e&cept those which will $ainly feed sulphide $inerals. Therefore* it will not be as i$por i$portant tant if a bloc8 of sulphides appears during an o&ides ca$paign and vice! vice!versa versa** as the treat$ent for o&ides and sulphides is si$ilar. )aCl *ddition System in *gglomeration
(orresponding to a new syste$ to be incorporated by the Full SaL project* this will allow for the addition of solid +a(l to the ore on the belt feeders that feed the agglo$eration dru$s. The operational philosophy is described below. )ormal Operation
The +a(l co$es fro$ the $anufacturing plant and enters the agglo$eration area in -2!ton truc8s. The truc8s will provide provide +a(l , days a wee8* 31 hours a day. The truc8s are weighed on a scale when entering and leaving the plant to control the weight of +a(l. 'fter being weighed* the truc8 first enters the escarp$ent area* and then travels to the unloading area* where it is positioned and the $aterial is unloaded onto a radial stac8er /)1!ST! -130. The radial stac8er consists of a feeder and a radial stac8er* and transports the $aterial to a 3*511 ton capacity +a(l stoc8pile. The discharge of salt is authorised by a beacon signal located in the unloading area* which will operate auto$atically. The $aterial is re$oved fro$ the stoc8pile using two variable speed belt feeders /)1!F?!-13 and -1-0* which discharge the +a(l onto the salt transport belts /)1!(V!-13 and -1-0. ?ach feeder belt asse$bly feeds an agglo$eration line* discharging the salt over belts )1!(V!112 and )1!(V!312* which correspond to agglo$eration lines +3 and +-* respectively. The +a(l supply syste$ design allows for the independent operation of each belt. ?ach +a(l belt feeder has a weigh $eter /)1!A?!-13 and -1-0* which will define the $ass flow of +a(l added.

The design includes transport of gases to a scrubber syste$ that uses 'C'S' water and pressurised air to abate the conta$inated gases* transferring the conta$inants fro$ a gaseous state into a solution. This solution is loaded into a tan8 where the water is re!circulated towards a wash syste$ and the re$aining solution is transported to the agglo$eration dru$s. The following figure shows the sche$atic of the process. Figure 33! - Scrubber Syste$ Sche$atic
)ormal Operation
The gases captured in agglo$eration and chutes are transported by ducts towards the e&pansion cha$ber. Before entering* inline flow $easure$ents are ta8en. The flow of gases entering the scrubber syste$ depends on the ventilation draft of the gases and the flow of wash water entering the syste$. The pH of the conta$inated solution is analysed inline and the reading is set with the flow $eter for discharge water and the 'C'S' water flow. Ahen the pH is less than 3* the solution is auto$atically discharged and the syste$ is reset with 'C'S' water until the pH is above 3. This operation can be continuous or discrete* depending on the characteristics and the volu$e of treated gases. The no$inal flow entering the scrubber is 3>*711 +$ 9:h and can operate with one or two functioning agglo$erators* as each gas collection syste$ has a da$per that can be opened or closed according to re
The nor$al shut!down includes the auto$atic shut!down of the scrubber syste$ and should be coordinated with agglo$eration plant shut!down procedures. The e
