Quantitative and qualitative estimation of iron in its ores is a crucial factor before its extraction. In this work, quantitative chemical analysis of iron was carried out from the collected seventy-two hematite samples from Pokhari, Nawalparasi. Sampling of the hematite ore was performed by channel sampling method. Chemical analysis was carried out by gravimetric, titrimetric, UV-Vis spectrophotometric and atomic absorption spectroscopic methods. The findings of different parameters in percentage areas follows: loss on ignition (1.76\u2009\u00b1\u20090.17), silica (47.06\u2009\u00b1\u20094.01), and iron (36.75\u2009\u00b1\u20092.50) by titrimetric analysis. Based on the chemical analysis, the Fe content in the collected hematite sample is in intermediate range. Thus, for the profitable iron extraction, other factors such as coverage of ores, extraction costs, and market value should be considered.<\/jats:p>","DOI":"10.1155\/2022\/4943823","type":"journal-article","created":{"date-parts":[[2022,8,31]],"date-time":"2022-08-31T17:50:11Z","timestamp":1661968211000},"page":"1-11","source":"Crossref","is-referenced-by-count":3,"title":["Chemical Analysis of Hematite Ore Collected from Pokhari, Nawalparasi, Nepal"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4689-0830","authenticated-orcid":true,"given":"Ram Bahadur","family":"Gharti","sequence":"first","affiliation":[{"name":"Department of Mines and Geology, Ministry of Industry, Commerce and Suppliers, Kathmandu, Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8326-3233","authenticated-orcid":true,"given":"Hari Bhakta","family":"Oli","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Amrit Campus, Tribhuvan University, Kathmandu, Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2900-7674","authenticated-orcid":true,"given":"Deval Prasad","family":"Bhattarai","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Amrit Campus, Tribhuvan University, Kathmandu, Nepal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"1","key":"1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.17741\/bgsf\/65.1.005","article-title":"Determination of ferrous iron in rock and mineral samples by three volumetric methods","volume":"65","author":"R.
