INTRODUCTION

2.3 PRESENTATION (cont’d)

The purpose of this manual is to provide information for operator training, with procedures for start-up, operation and shut-down of the process plant facilities. It is intended primarily for the use of the plant operating staff and therefore does not contain details of equipment or instructions for equipment maintenance.

Information relative to init ial starting of equipment presented in sequence of start-up for operator reference.

is

PROJECT DESCRPTION

4.1 GENERAL The scope of work the Cobriza Expansio n Project covers mine development, mine equipment, new process plant, expanded or new support services and facilities, townsite housing, land development and townsite services. The new process plant replaces the existing process plant. The new process plant receives run-of-mine ore from bottom dump rail cars discharging to the primary gyratory crusher. The ore is then crushed, ground and concentratred by flotation. The copper concentrate is thickened and filtered and discharge to final concentrate storage. Trucks are loaded with concentrate by front end loader for transport to a smelter. The tailings are thickened and filtered and discharged into the Mantaro River by gravity. Water for the new process plant is obtained from the Rio Huribama. Water flows bye gravity to storage tanks at elevation 2387 m, providing sufficient pressure (by gravity) at the concentrator.

PROJECT DESCRPTION

4.2 PROCESS (cont’d) a) Electrical Power Supply and Distribution System Electrical power will be supplied from the Rio Mantaro power system through a 60 kV transmission line, terminating at two 60/10/4-16 kV transformers located within the substation enclosure on Pampa de Coris. The proces plant power distribution systems are fed from these two transformers based on teh two (2) bution and 4.16 kV for large motors such as the grinding mill motors. The transformer secondaries are connected to switchgear also located in the substation. This switchgear then d istributes both 10.0 kV and 4.16 kV to switchgear/motor controllers mounted in lectrical control rooms located in the Primary Crushing Building, Fine Crushing Building, Grinding Building and Flotation Building. The electrical control rooms are located to provide minimum length of run to the specific point of use. b) Water Supply and Distribution System

Electrical power is supplied from the Rio Mantaro Power System through a new transmission line terminating at new transformers located within the substation enclosure on Pampa de Coris, north of the new process plant.

4.2 PROCESS The new process plant is designed to process 3,500,000 stpy of ore at a nominal feed rate of 10,000 stpd and, by conventional flotation concentrating techniques, produces 224,000 stpy of copper concentrate essaying 25.4% copper.

Water for the process plant is obtained from the Huaribamba River, utilizing the existing intake and settling basins. The water flows by gravity through a pipeline to two storage tanks at elevation 2387 m, providing sufficient pressure (by gravity) at the process plant. One tank holds the fire water reserve in the lower portion of the tank and fresh water supply above the fire water reserve. The other tank holds process water made up of river water and up to 50% reclaimed process water from the tailings thickener overflow settling pond. Fresh make-up water is discharged into the settling pond to mix eith the reaclaimed water before it is pumped to the process water storage tank. c) Primary Crushing and Coarse Ore Storage

The ore, consisting primarily of massive sulfides, c ontains an average of 1.8% copper in chalcopyrite mineralization.

This portion of the plant extends from teh run-of-mine ore feed to the primary crusher, through primary crushing and coarse ore storage.

In this manual, the ore concentrating plant is divided into seven (7) major parts: Electrical Power Supply; Water Supply; Primary Crushing and Coarse Ore Storage; Grinding, Flotation, Thickening and Filtering; Reagent Processing, Storage and Distribution: Tailings Disposal; Process Sampling; and Misceññaneous Ancillary Facilities.

Ore is reclaimed from the fineore storage stockpile by three variable speed belt feeders, discharging material onto a belt conveyors which conveys the ore to a first-stage grinding ball mill. A belt scale is installed on the conveyor for feed control and to continuosly measure the flow rate and total tonnage of material being fed to the grinding circuit. Primary grinding is performed in two stages. The first stage ball mill is in closed circuit with a bank of hydrocyclone classifiers. First stage classifier overflow reports to the discharge sump of the second stage mill, which is also the feed sump for the second stage cyclone. The second stage mill discharge and the overflow from the first stage hydrocyclone report to a bank of second stage hydrocyclones in closed circuit with a second stage grinding mill. Second stage classifier overflow is finished flotation feed reports to agitated conditioning tanks.

Rougher – Scavenger Flotation

General

Overflows from the conditioning tanks are treated in two identical parallel rougher-scavenger flotation circuits.

Maintenance of the equipment within the grinding area is performed by a 25/5 short ton capacit y overhead travelling brid ge crane and maintenance of the equipment within the flotation area is performed by a 10 short ton overhead travelling bridge cranes are serviced by monorail hoists.

Regrind hydrocyclone overflow is combined with the flow from the conditioner tanks and pumped to Rougher I flotation. Tails from Rougher I flotation flows to Rougher II flotation , thence to Scavenger I flotation and thence to Scavenger II Flotation. Scavenger II flotation tails flow to the final tailing sump and then to the tailings thickener. Rougher I concentrate is pumped to second Cleaner flotation and Rougher II concentrate is pumped to First Cleaner flotation. Scavenger II flotation concentrates are combined and then pumped to regrind.

Mill liner maintenance is performed with an electric/hydraulic liner handling machine. Services in these areas also include floor sumps and pumps.

Cleaner Flotation Upgrading of concentrates from Rougher I and Rougher II slotation is accomplished in three cleaner flotation stage utilizing countercurrent flow of tails. Rougher II flotation concentrate and Second Cleaner flotation tails are combined and then pumped to First Cleaner flotation. Rhe resulting tails report to regrind and the concentrate is combined with Rougher I flotation concentrate and Third Cleaner flotation tails and then pumped to Second Cleaner flotation. Second Cleaner concentrate is pumped to Third Cleaner flotation and the resulting concentrate is then pumped to the concentrate thickener. Regrind Sacvenger concentrates and First Cleaner flotation tails are combined, forming the feed for regrind. The regrind circuit consists of two parallel circuits each with a ball mill in closed circuit with a bank of hydrocyclone classifiers. The feed is split between the two regrind circuits bye means of a static distributor. The hydro-cyclone overflow is combined with the conditioner tanks overflow is combined with the conditioner tanks overflow and reports to Rougher I feed pumps.
