Engineering Consulting

I Purpose of Engineering Consulting

Engineering consulting makes clients have a comprehensive understanding of the value of mine, the useful elements, available mineral processing technology, plant size, required equipment and period.
II Contents of Engineering Consulting

Xinhai Technology Support Department is responsible for engineering consulting. When a client needs engineering consulting, firstly, Xinhai Research Institute will arrange an expert with rich dressing experienced to make sure the ore preparability according to the analysis of mineral elements (Xinhai also makes this analysis). The basis of experts relying on in the mineral elements analysis mainly includes: elements content (number, type), elements distribution, recovery rate of useful elements etc.
After making sure the ore preparability, Technology Support Department would contact with mineral dressing construction departments including geology, mining, ore dressing, smelting, machinery, civil engineering, electric power to get a brief quotation.
Xinhai mine consulting provides services according to the need of clients. The information clients providing is more detailed, the information of mines consulting is more detailed and accurate. The main contents of mines consulting include mining, mineral processing, external conditions, investment estimation and analysis of economic benefit.
The engineering consulting illustrates all the problems in the construction of dressing plant according to the limited information provided by the clients, so the experience of expert is a key. Only an expert with rich experience could provide detailed engineering consulting for the clients, which allows clients to have general understanding to their own mines and the value of dressing plant.
III Results of Engineering Consulting

At last, engineering consult takes on economic benefits analysis for the customers including the cost analysis and profit estimate. Economic benefit analysis is a comprehensive quotation by Xinhai Technology Support Department connecting various departments (Civil Engineering Department, Processing Department, Mining Department, Electric Power Department, etc.). Mine costs include mining, transportation, mining beneficiation, financial management cost. Profit estimate includes ore grade, product, price, annual output, total income, total cost, profit before tax, comprehensive estimation (time of recovering the investment).
Economic benefit analysis will allow clients to have a rough understanding about the investment and earnings of mine, and guide future investment.

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.

Mine Design

Three parts of mine design: feasibility study, preliminary design and construction plan
The key of mine design is all must be established on the basis of detailed investigation, and therefore Xinhai Mine Design Institute will firstly take a comprehensive field study to the mine of clients including the crude ore for dressing plant, site, water, electricity, traffic, geography, etc..
These investigation contents need the cooperation of geology, mining, ore dressing, smelting, machinery, civil engineering, electric power and other departments
