The influence of organic polymer on properties of mineral concentrates Part I

Abstract

The property is evaluated when acceptance for loading of solid bulk cargoes is judged prior to shipment. The liquefaction can be prevented by means of limiting the moisture content of the cargo by introducing the safety margin, regardless of the condition of stresses. It is rational to limit the moisture content of cargoes, which may liquefy, because liquefaction is not liable to occur when the degree of saturation is low, even if the permeability of the material is low. To prevent sliding and shifting of ore concentrates in storage biodegradable thermoplastic materials were added to the ore. The polymer absorbs water from the particle pore in mineral concentrates and its moisture content goes down. In consequence, polymer prevents: drainage of water from the particle pore, sliding and shifting of ore concentrates in storage.
