摘　　要：自然界中锡主要以氧化物和硫化物的形式存在,原生锡矿石通过单体解离后,采用粗粒重选、细粒浮选、离心机富集等方式选别出最终合格锡精矿,某企业的锡精矿产品含锡35%左右,硫+砷小于3%,选别后的锡精矿产品通过购销的方式交收至冶炼,但在交收过程中需通过过磅、取样、化验等环节反应产品质量,确保购销的公平、公正。鉴于锡广泛的应用领域和较高的经济价值,如何确保锡精矿产品在销售结算过程中的规范运行,在过磅、取样、化验等环节提出了更高的要求和精度。因此开展锡精矿产品交收质量影响因素的分析研究,提升销售各环节的规范管理,促进交收过程的质量保证、减少经济纠纷具有重要意义。Tin in nature mainly exists in the form of oxides and sulfides.After the primary tin ore is separated by monomer,the final qualified tin concentrate is separated by coarse-grained gravity separation and fine-grained flotation,etc.The tin concentrate product of an enterprise contains about 35% tin,and the sulfur + arsenic is less than 3%.The sorted tin concentrate is transferred to the next process for smelting.However,in the settlement process,it is necessary to reflect the product quality through weighing,sampling,testing and other links to ensure the fairness and justice of the purchase and sale.In view of the wide application field and high economic value of tin,how to ensure the standard operation of tin concentrate products in the process of sales and settlement,higher requirements and accuracy are put forward in weighing,sampling,testing and other aspects.Therefore,it is of great significance to carry out analysis and research on the quality control of tin concentrate product settlement,improve the standardized management of all aspects of sales,promote the quality assurance of settlement process and reduce economic disputes.
