摘要

提出了一种以詹姆斯锑矿精矿为原料，采用连续真空分解法制备金属铅，同时生产硫化锑产品的方法。在650℃、10 Pa条件下分解，得到纯度超过99%的硫化锑。同样，纯度超过99%的硫化铅在750°C和10 Pa的条件下生产。粉末状的硫化铅随后被球磨并压成块状，然后在1050℃和10pa下分解，得到纯度超过99%的金属铅。该方法环境友好、无公害，实现了从脆硫铅锑精矿中以流线型工艺制取金属铅的目的。此外，它还为从这类精矿中制备金属铅提供了一种新的方法。

Preparation of metallic lead from complex lead-antimony sulfide ores by continuous vacuum distillation

A method for the preparation of metallic lead from jamesonite concentrate via continuous vacuum decomposition, simultaneously yielding antimony sulfide products was proposed. By decomposing at 650 °C and 10 Pa, antimony sulfide with a purity exceeding 99 % was obtained. Similarly, lead sulfide with a purity exceeding 99 % was produced at 750 °C and 10 Pa. The powdered lead sulfide is subsequently ball-milled and pressed into blocks, which are then decomposed at 1050 °C and 10 Pa to yield metallic lead with a purity exceeding 99 %. This method is environmentally friendly and pollution-free, achieving the objective of preparing metallic lead from brittle sulfur lead antimony concentrate through a streamlined process. Additionally, it offers a novel approach for the preparation of metallic lead from such concentrates.

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
