Coal plays a vital role in the economic development of the world as the primary energy. In
recent years, hazardous elements emission from coal utilization has attracted considerable …

Jig separation, one of the oldest and most widely used methods in mineral processing that
separates particles based on density differences, was applied to recover valuable materials …

Moisture content has an important influence on the stratification and screening of materials
on the surface of screens, and materials with different external moisture concentrations …

A modified jig called the hybrid jig was recently developed to separate mixed-plastics with
similar specific gravities effectively using the concepts of bubble attachment, surface …

We have developed the hybrid jig which combines the principles of jig separation and
flotation. However, the selectivity of bubble attachment in water was poor because most …

The hybrid jig, which combines the principles of jig separation and flotation, was recently
developed to separate mixed-plastics with similar specific gravities (SG) effectively. In this …

Coal preparation is the basis and prerequisite for clean coal utilization. Air dense medium
fluidized bed separation (ADMFB) technique demonstrated good separation performance for …

The dry separation of fine coal provides a feasible, low-cost and pollution-free method for
the pre-arsenic removal from coal prior to combustion. In this study, the arsenic (As) …

This paper proposes pre-beneficiation studies by air jigs of the coal layers from a Moatize
coal deposit. Pre-beneficiation, also called destoning, removes tailings before the …

Large-scale experiments were conducted using an FGX-3 dry separator to beneficiate a
Chinese coal. The separation results indicated that the FGX separator provided ash …
