Introduction

Mining operations generate significant amounts of tailings, which require effective management and disposal. Dewatering presses are vital in processing these tailings, enhancing their stability and reducing environmental impacts. This article delves into the mechanics of dewatering presses and highlights their role in mining operations.

Operation of Dewatering Press

A dewatering press applies mechanical pressure to remove water from mining tailings, producing a dry, compacted product. The process involves several critical components and stages:

• Feed Slurry Introduction: Tailings in slurry form are fed into the press, typically with a solids concentration of 20-30%.
• Filter Cloths and Plates: The slurry is distributed across filter cloths stacked between filter plates, which are often made of polypropylene.
• Pressure Application: Hydraulic or mechanical systems apply pressures up to 20 bar, or about 290 PSI, to expel water.
• Water Collection and Discharge: Separated water is collected in a drainage system and discharged, often with recovery rates exceeding 90%.
• Cake Formation: The remaining solids form a filter cake with moisture content ranging from 10-25%, depending on the press type and tailings characteristics.

Advantages of Dewatering Press in Mining

Implementing a dewatering press yields numerous benefits for mining operations:

• Volume Reduction: Dewatering significantly decreases tailings volume, easing storage and handling.
• Environmental Impact: Reduced water content minimizes leakage and contamination risks, aiding compliance with environmental regulations.
• Water Recovery: High recovery rates facilitate recycling and lower operational water costs, crucial for sustainability in arid regions.
• Cost Efficiency: Although initial investment is substantial, operational savings and regulatory compliance can lead to cost benefits.
