Test for Mineral Processing Design

Research contents

Purpose

1.The processing mineralogy of ores experimental studies

1.Analysis by Chemicals method
1）Ore spectroscopy
2）Ore multi-element analysis
3）Mineral phase analysis
2. Ores identification
1) Mineral species and the relative content
2）Major minerals granularity properties and disseminated size
3）The characteristics of the main minerals
4）Occurrence and distribution of associated precious metals and other valuable metals;
5)sequence of the Minerals occurrence

Identify valuable elements type and content.
Identify the oxidation rate of the target elements.

1.Identify the types and relative content of valuable minerals in the ore, the types and content of the gangue. Mineral symbiotic relationship

2.Identify the structural configuration of valuable minerals and ores granularity

3.The existence state of elements with comprehensive recycling to guidance flotation tests.

Mineral separation experiments

1. Flotation tests
