Xinhai improves the traditional specification of crushing chamber by adopting high speed swing jaw and cambered jaw plate.
High-speed hammer impacts materials to crush materials. There are two ways of crushing (Wet and dry)
The cone slide valve is adopted; the failure rate is reduced by 80%; low energy consumption;the separation of different material, improvement of the processing capacity by more than 35%.
Cylindrical energy saving grid ball mill is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding.
20-30%. Rolling bearings replace slipping bearings to reduce friction; easy to start; energy saving 20-30%
Both sides of the impeller with back rake blades ensures double circulating of slurry inside the flotation tank. Forward type tank, small dead end, fast foam movement
In an effort to recover additional copper and gold at KGHM Internationals Robinson. Mine located flotation recoveries from the concentrators final tailings stream. Tests were Currently, the Robinson Operation is mining porphyry-skarn deposits The SAG mill discharge is further ground with two 20 x 31 micron P65.
El Dovio property has the potential for Gold exploration, gold copper zinc ores, and has purchased 100% of the surface rights covering the same ground at El Dovio. Flotation tests were conducted on a bulk composite sample selected to to 80% passing 75 microns 200 mesh, a prevalent grind size in modern mills.
Aug 22, 2009 The flotation of a natural porphyry copper ore with bornite and malachite each charge was ground with 477 mL of tap water 65 ww % solids in a for 55 minutes using a vibrating 20 micron 635 mesh screen and.

This paper discusses the effect of wet and dry grinding on copper flotation of a complex Cu-Pb-Zn ore. It has reported that for <600 micron feed, grinding mode had no effect on The recovery of sphalerite is higher when it is ground in a dry.
Upgraded concentrate from the bulk flotation process feeds the copper- Finely ground ore flows through a series of flotation equipment: first through two banks trash screen which released high froth, very fine particles <50 microns.
Porphyry Copper Deposits with Emphasis on Potential Future .. occur as a trace element within these sulfide minerals or as micrometer-scale grains of .. data to screen numerous samples, which are followed by the more laborious kinetic . that beneficiation of ore can have on mine tailings derived from froth flotation.
May 10, 2002 Titanium, Rutile, Porphyry Copper Deposits, Hydrothermal Alteration, Introduction of a flotation circuit for rutile recovery at Chuquicamata proximal method was most effective because the soil samples showed samples the highest percentage of grains occur at about 100 microns or 100 mesh size.
Surface geochemical prospecting involves analyzing soil, rock, water, The copper ore bodies mined from 1911 to 1938 at Kennecott, Alaska now within the an amount of copper equivalent to a 100-million-ton typical porphyry copper as 3.3 millimeters 6 mesh and as small as 5 microns and can handle minerals
The need for copper and molybdenum continues to grow as does the need for clean Traditional treatment of copper porphyry ores bearing molybdenum consists of Figure 1: Typical Copper and Molybdenum Differential Flotation Circuit. .. and approximately 0.9% molybdenum and ground to approximately 10 microns.
