The Feasibility Test of Physical and Chemical Peoperties of Muaro Binguang Pasaman Barat Iron Sand for Semen Padang

Abstract

The purpose of this study was to examine the physical and chemical feasibility of iron sand on the west coast of Muaro Bingguang west Pasaman. This research needs to be done because the west coast of the island of Sumatra is known to be rich in iron sand and Semen Padang as a large company in West Sumatra needs iron sand to mix its cement. Test physical properties by calculating specific gravity, determine the characteristics of iron sand, and susceptibility of iron sand magnets. 5 sample bags were taken at coordinates S004′46.49 ″E99046′6.33″, S005′8.93 ″E99046′2.34″, S007′39.40 ″E99045′25.60″, S008′20.60 ″E99044′55,5″, and S008′39.00 ″E99044′55.4″. While the chemical feasibility test is done by testing the sample using XRF. The results of this study obtained, the average iron sand density of 2.99-4.23, iron sand including superparamagnetic with magnetic susceptibility 4,947 ×10-6m3kg-1- 14,946 ×10-6m3kg-1. Based on XRF analysis, iron sand is in accordance with Padang's cement needs in making portlant cement Fe2O3 = 10% - 35% and TiO2 = 1% - 3%.
