The Study on Copper-Molybdenum Polymetallic Mine Ore-Controlling Structure Conditions and Mineralization Forecast of the Jiudingshan

Abstract

JiuDingshan copper-molybdenum polymetallic mine located in the "Sanjiang" metallogenic belt Southern Section, is typical of copper molybdenum deposit related to porphyry activities. Mining area is located in Erhai - honghe fault and Chenghai - binchuan fracture clamping of the triangle,Lijiang-heqing porphyry Cu-Mo-Au mineralization zone and the alkali rich porphyry clusters, the tectonic background of mining area is complicated at the same time, strong tectonic activities, has the very good ore-forming geological conditions and great prospecting potential.

Modeling the distribution of rock mass and native copper output by size classes during crushing

“…In about 10% of cases, flotation yields 82 % recovery and very rarely 85 %. The same applies to the gravitational enrichment of non-ferrous metals, where the typical recovery is 60-70 %, not higher than 80 % [25][26][27][28].…”

Research of the properties of quarry tuff-stone for complex processing

“…In the process of research of zeolite-smectite tuffs, which occur in large quantities in Rivne-Volyn, their magnetic susceptibility was established, which is explained by the presence of iron and titanium. Quantitative and qualitative analysis of the content of these elements was performed experimentally using magnetic and spectral analyzes of crushed tuff-stone samples of different sizes at variable magnetic field strength to determine the level of its sufficiency in the ore preparation of raw materials for complex processing [24][25][26][27].…”
