Gold are mainly hosted in limonite and quartz.
Effect of sample preparation on determination results of total iron content in limonite
It's a mid scale and its ore belongs to low grade structural altereds tyle, limonite, pyrite are mainly gold carriers.
It brings forth a novel solution for the exploitation and utilization of analogous high-phosphorus hematite-limonite ore resources.
Native gold as fine grains and micro grains occurs in pyrite, arsenopyrite and limonite. Gold ore is intensively oxidized and characterized by low impurity and easily sorting.
Glauconite, hematite-limonite and some chlorite are formed in syndiagenesis.
In the condition of laboratory test, sintering experiments were carried out with full limonite blend.
Research and Industrial Practice of Beneficiation Technology on Low-grade Fine-grained Refractory Siderite-limonite of Daxigou
The typical characteristic of the ore is low sulfide. The metallic mineral has very few content (1%-2%), the mineral of ore is mainly of pyrite, chalcopyrite, limonite, aurum and electrum etc.
The contents of organic material, limonite and manganese hydroxides influence the variation of ore element.
Iron minerals in an iron ore of Shanxi are mainly limonite and hematite, and gangue minerals are mainly bauxite, kaolinite, mica, phosphate rock and so on.
However, assimilation of limonite is better and the capability of creating calcium ferrite is higher by 20% than other ores. The reducibility of limonite is better.
A series of experimental studies were made on the effect of amide collectors with different length of carbon chain on flotation behaviors of hemimorphite quartz dolomite and limonite.
Under weathering carbonates, such as siderite are usually turned into limonite which finally occur as hematite in the Weathering crusts.
Laboratory and industry experiment about adding limonite in sintering are introduce in the paper, expound reinforcing measures of limonite sintering.
Ore types are limonite fractured silicic sandstone, quartz veinlet and bedded flysch rhythm ore.
