Mineral Dressing Test

Mineral Dressing Test

Mineral dressing test is in charge of Mineral Dressing Research Institute belonging to Xinhai Company

I Preparation before test

The clients should provide about 50g representative samples some special samples about 2001000g. The simple test needs 30 working days and the detailed test about half a year.

Sign the test contract with clients before the mineral dressing test and make sure dressing Process to test

II Testing Process

1. Chemical Lab of Mineral Dressing Research Institute analyzes the material components ore structure mineral and types of ore and chemical properties elements the particle size screening density ore relative grindability of crude ore and gets some data for the subsequent beneficiation test.

2After the working of Chemical Lab Mineral Dressing Research Room takes the mineral beneficiation test which tests the optimum conditions of dressing Process. Testers take the exploratory testing at first relying on rich experience and then the detailed testing including grinding fitness reagent dosage open and closed circuit test etc. After obtaining the final productstesters should analyze them to get the recovery rate and then takes sedimentation test of concentrate and tailings as references of equipment selection.

III Test results

After finishing all the tests Mineral Dressing Lab writes a detailed Mineral dressing test report by summarizing the test Process. In the last part of test report the optimum technological Process and technological parameters are presented.

"Mineral dressing test report" is important basis of next mine design and brings significance of guiding actual production.

Notes Recovery rate is the final result of mineral dressing test and the core of dressing plant construction. Every 1 reduction of recovery rate cause huge losses especially in gold silver mine so the purpose of mineral dressing test is to get the recovery rate as high as possible in order to reduce the loss of clients.

Xinhai Mineral Dressing Research Institute

Xinhai Mineral Dressing Research Institute belonging to Xinhai Mining Machinery Co.Ltd is divided into Mineral Dressing Research Room andChemical Room. Mineral Dressing Research Room is responsible for mineral dressing test the Chemical Lab for the chemical composition analysis of crude ore products intermediate products final products and other samples.

The expert teams of Xinhai Mineral Dressing Research Institute consist of the professionals who enjoy government special allowance of the State Council or retired from University. Xinhai Mineral Dressing Research Institute could independently contract foreign projects and mainly carries on the research of gold non-ferrous metal and ferrous metal. The number of projects carried on every year is about 60.

Each dressing test of Mineral Dressing Research Institute is in strict accordance with the following steps the following table data is from the relevant dressing test data of a client

I Preparation of sample

This part is described as preparation of sample used in test. The following sample Process flow chart and preparation table is provide for clients

II Crude ore properties determination

The crude ore properties determination includes ore material component determination and ore chemical properties determination

II Crude ore properties determination

The crude ore properties determination includes ore material component determination and ore chemical properties determination

1Ore material component determination

The ore material component determination includes instruction types and components of ore metal and non metal mineral characteristics. The following part of chart presents the ore material component determination

2Ore chemical properties determination

Ore chemical properties determination includes crude ore multi-element analysis to make sure the ore if comprehensively recycled and used crude ore particle size screening analysis ore density determination and ore relative grindability test. The following is related charts of ore tests

III Mineral dressing test

Mineral dressing test includes exploration test and mineral dressing conditions test

Exploration test primarily explores the mineral dressing conditions and then gets better Process condition. The detailed test follows the Process condition determination including grinding fineness test reagent test open circuit and closed circuit test. The following is part of the chart of exploration test and detailed test for customers.

IV Final analysis result

This step takes the valuable element analysis and screening analysis of valuable mineral concentrate and tailings and gets the recovery rate of valuable mineral

V Sedimentation test

Sedimentation test as reference of equipment selection aims to concentrate and tailings of valuable mineral. The flowing is the sedimentation test result of Pb concentrate
