Construction of the PivnGZK Recycled Water Supply Pumping Station.
Leading specialists of M Technology visited the Northern Mining and Processing Plant, where construction of a tailings thickening complex is underway under the company’s project.
The purpose of the complex:
Is to reduce electric power consumption associated with high-volume tailings pumping processes. This is achieved through implementation of tailings thickening technology.
The complex also includes a Reverse Water Supply Pumping Station (RWPS), the process design of which was developed by M TECHNOLOGY. The project partner and equipment supplier is HABERMANN AURUM PUMPEN.
Reverse Water Supply Pumping Station (RWPS).
The Reverse Water Supply Pumping Station is designed for accumulation and uninterrupted supply of clarified process water to Concentrating Plant No. 1 and is classified as a Reliability Category I.
Technology Overview.
Clarified water from the thickeners flows by gravity through four pipelines into the pumping station receiving tank. The pumping equipment then delivers the water for process purposes of the concentration plant.
The project provides for the use of Habermann Aurum Pumpen pump units with a capacity of up to 7,300 m³/h and a head of 88 m of water column.
An additional pump unit is also included in the project, making possible flexible regulation of water supply according to production requirements and providing system redundancy.
Water is supplied through six main pipelines with continuous monitoring of pressure, flow rate, and water level in the receiving tank. Operation of the pumping equipment and switching of the pipelines are integrated into the plant-wide supervisory control and dispatching system.
To ensure reliable operation, the following systems are provided:
– automatic standby operation of pumping equipment;
– emergency water discharge and drainage system;
– phase-in operation of pumps and pipelines;
– monitoring of operating conditions through the supervisory control system.
The RWPS also includes electrical rooms, an operator control room, auxiliary service facilities and a flowmeter maintenance unit.
Lifting devices including a 12.5-ton overhead electric crane are provided for equipment installation and maintenance in the machinery hall.
Company specialists visited the construction site and participated in the commissioning of the Aurum Pumpen pumping equipment.
Conclusion.
The pumping station process scheme ensures an uninterrupted supply of clarified water, required for operation of the tailings thickening complex.
Supply of modern pumping and auxiliary equipment with integrated automation systems, ensuring reliable operation of the facility, is part of the project and has already been implemented.
Construction is planned to be carried out in four stages. Completion of the first stage is scheduled for the first quarter of 2027.
