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 200~1000g. 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.

2、After 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 products,testers 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 and Chemical 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)
