The pulp rheology is an important factor affecting flotation performance. Gangue minerals have a significant impact on the rheological property of smithsonite (ZnCO3). complex (high viscosity, poor dispersion) will adversely affect grade and recovery concentrate. To address this problem, effect gangue (kaolinite, calcite, quartz) behavior was investigated with measurement test. results showed t...

We demonstrate a simple strategy to either prevent or enhance hydroxide incorporation in nanocrystalline solid-state metathesis reaction products prepared in ambient environments. As an example, we show that ZnCO3 (smithsonite) or Zn₅(CO₃)₂(OH)₆ (hydrozincite) forms extremely rapidly, in less than two minutes, to form crystalline domains of 11 ± 2 nm and 6 ± 2 nm, respectively. The phase select...

The thermal decomposition of smithsonite (ZnCO3) was studied to obtain a universal kinetic description the process applicable range reaction conditions. A synthesized ZnCO3 subjected...

Motivated by the construction of new examples of Artin-Schelter regular algebras of global dimension four, J.J.Zhang and J.Zhang (2008) introduced an algebra extension AP [y1, y2;σ, δ, τ ] of A, which they called a double Ore extension. This construction seems to be similar to that of a two-step iterated Ore extension over A. The aim of this paper is to describe those double Ore extensions whic...
