EDX8800M MAXAnalytical determination for nickel ore

1. Background Introduction

For a long time, the primary source of nickel metal production has been magmatic sulfide ores. However, as global demand for nickel metal increases...Resources are increasingly in demand. One source of nickel is laterite, which is typically mined as a low-grade ore deposit in open-pit mines. In order toOur nickel production process has been optimized, enabling us to monitor the chemical composition of nickel more accurately than ever before.Important. In addition to the constant elements such as Ni, Fe, etc.,Silicon (Si), Magnesium (Mg), Aluminum (Al), Calcium (Ca), Titanium (Ti), Chromium (Cr), Manganese (Mn), Cobalt (Co), Copper (Cu), and Zinc (Zn) are typically present as trace elements.All these elements can be detected using the EDX8800 MAX Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometer.The instrument provides a rapid and accurate control over the mining process and the subsequent mineral processing.

4 Sample Preparation Methods

Sample Preparation:

For rapid process control, the sample preparation can be done using the compression method. Due to the straightforward sample preparation process, analytical results can be obtained within minutes after sampling. For the compression method, we take 10.0 g of the milled 200 mesh nickel ore sample and mix it with 2.5 g of wax binder, then press it to 20 tons for 15 seconds using a press machine.

For the fusion method, it eliminates any influence from the mineralogical matrix, thus allowing for the measurement of a wider range of samples from different open-pit mines. The fusion method requires 0.80 grams of ore sample and 8.00 grams of flux (50% lithium metaborate + lithium).High-temperature processed in a melt-blanking machine to form the sample for testing, containing 50% of boric anhydride.

The tablet manufacturing process is illustrated as shown in the above figure.

The melt-blown film production process is illustrated as shown in the above figure.

Samples were measured under vacuum conditions after preparation, eliminating the need for expensive helium as a purge gas. This measurement condition significantly reduced costs.
