红土镍矿化学成分的相关性探析

Study on Relationship between Chemical Components of Laterite Nickel Deposit

摘要:

红土镍矿进口量大、成分复杂、差异性大。为全面了解红土镍矿中各化学成分的相关性，以日照港为主，连云港、天津港为辅，从2013年1月—12月，按进港量多少，每月抽取11~25个样本，共228个。通过元素分析，检出主要元素19个，逐对分析相关性。发现地质作用造成的多元素共生关系，也有外部环境风化淋滤后的弱相关、不相关，甚至有风化淋滤过程中形成的强相关。

Abstract:

Laterite nickel deposit has the characterisitcs of large imports, complex compositions and high differences. In order to fully understand the correlation between chemical compositions of laterite nickel ore, taking Rizhao Port as the main study area, supplemented by Lianyungang port and Tianjin port, from January to December in 2013, according to the amount of monthly arrivals, extracting 11~25 samples every month and the 228 samples in total, through element analysis, the correlation between 19 major elements has been analyzed. It is found that there are symbiotic relationship between many elements caused by geological effects, weak correlation or no correlation caused by external environment weathering leaching, even strong correlation caused by weathering and leaching.
