Ali Mokhtari, the project manager:
The main process in mineral processes is the concentration of a mineral, that is, raising the concentration of the desired element in the soil extracted from the mine to such an extent that the concentrated material can be sold in crude form or can be sent to other stages as a mill feed.
Renovation of Concentrator In Sarcheshmeh Copper Plant
Client: National Iranian Copper Industries Co
Implementation Duration: 24 months (2018)
Project Description
In Sarcheshmeh Copper Plant, most factories and departments are engaged in the process of converting soil to copper concentrate, as approximately 60% of the departments are a subset of concentrations.
About 40 years have passed since the start of the Sarcheshmeh Copper Plant, most of the equipment has either reached the end of its useful life or equipment with higher technologies has entered the market as an alternative; As a result, the need to change equipment and upgrade technologies has become more acute. In the meantime, some problems or the need to make some corrections were also observed in processes, equipment, structures and parts, which should be addressed seriously and quickly.
Since 2010 and with the emphasis on the need to make corrections and eliminate defects in equipment, the department of concentration in Sarcheshmeh assigned ANIN Co. as the most efficient consultant for concentrating the Sarcheshmeh copper plant the responsibility of reviewing, conducting technical and economic studies, drawing financial models, preparing plans, documents as well as basic engineering and detail documents, and consulting services, and providing tender documents, meters and project implementation estimates.
In this regard, after operation units had announced that there were problems in systems and equipment, the cases were fully identified and meetings were held to review the problem and the method of solving them. After holding meetings and convincing the client, a project in this regard was defined based on the various solutions that have been presented.
Later on, our team in ANIN Co. while preparing the aforementioned items for each project, holding the tender and supervising the selected contractors, the project was completed and devices were handed over to users after eliminating the shortcomings.
Some of the projects that have been implemented so far in order to reconstruct and develop the Sarcheshmeh Copper Plant concentration department are as follows:
Using the Jumbo bag filling system in parallel with the Drum filling system in the molybdenum concentrate factory
Replacement of the set of primary screws and feeders in the zero-concentration crushing plant
Production of chemical fertilizers, food supplements and ferrous sulfates
Production of refractory magnesia chromite bricks
Production of needed lime for the factory
Production of zinc alloy, lead, copper
Concentration of single filter filtration system
Improvement of condensation injection system
Production of precision sensitive alloy parts by powder metallurgy method
Production of hydrated copper sulfate
Modification of conveyor speed control system 2051
Modification of control system of primary and secondary cyclone pumps
Replacement of drives and electromotors of sag mill and ball mill of the 2nd Phase of concentration
Replacement of magnetic clutches and soft starters
Development of a lime unit to use the hydrated lime needed by concentration plants
6 and 9 conveyor belt drive system
Injection of dry lime into sag mill no.1 and 2nd Phase of concentration Plant
Construction of phase 3 of concentration expansion
Construction of tailing thickener No. 6
Rotation of Til thickener lines in the overhaul
