ACZ Laboratories, Inc. has over 40 years of experience providing analytical support to the mining industry and has built a reputation as one of the highest-quality environmental laboratories in the industry. ACZ provides analytical support services to gold, silver, rare earth, copper, coal, trona, soda ash, base metal, and\u00a0<\/span>uranium mining\u00a0<\/span>operations. We currently support mining operations throughout the United States, Central & South America, Africa, as well as Asia.<\/p>\n ACZ understands the analytical requirements and data quality needs of the modern mining industry. We deal with the unique water matrices that are associated with mineralized zones around mining operations on a daily basis. We also perform specialized mining-related testing and sample prep in-house on overburden, ore, mine tailings, plant tissue, and animal tissue that many labs have to subcontract. This overall turn-key experience is why so many mining companies and their consultants choose ACZ for their analytical work. Unlike most of the large chain laboratories, we do all analyses in-house at one single location.\u00a0 We do not have to send out samples to a separate satellite lab in order to perform full suites of analytical parameters.<\/p>\n Acid\u2013Base Accounting is a dependable criterion by which overburden materials can be evaluated. An acid-base account consists of two measurements: 1) total or pyritic sulfur and 2) neutralization potential. The accounting balances the maximum potential acidity against total neutralizers in the sample.<\/p>\n The total or pyritic sulfur content accurately quantifies potential acidity of materials when all sulfur is present as a pyritic mineral. When gypsum is found in an overburden sample or the materials are weathered, sulfur occurs in the form of sulfates. Samples high in organic carbon usually contain organic sulfur. When part of the sulfur occurs in non-acid-producing forms, the maximum potential acidity, as calculated, will be too high. It is for this reason that such calculations are referred to as maximums and that in doubtful cases, appropriate acid and water leachings should be made to rule out those forms of sulfur that do not produce acid. Then, from the stoichiometric equation of pyrite oxidation, the maximum potential acidity can be calculated in terms of calcium carbonate required to neutralize 1000 tons of the material. The neutralization potential of overburden materials (the second component of a net acid-base account) measures the amount of neutralizers present on the overburden materials. This measurement is found by treating a sample with a known amount of standardized hydrochloric acid, heating to assure complete reaction, and titrating with a standardized base. The result is then expressed in calcium carbonate equivalents. When balanced against acidity from the total sulfur measurement, a net acid-base account can be made.<\/p>\n ACZ Laboratories holds certification from the State of Nevada for Acid-Base Accounting methods. Nevada is currently the only state agency offering this certification.<\/p>\n <\/p>\n [\/et_pb_text][et_pb_image src=”\/wp-content\/uploads\/2021\/02\/Humidity-Weathering-Cells-HCT-1-Web.jpg” alt=”Humidity Weathering Cells HCT, Geochemistry” title_text=”Humidity Weathering Cells HCT, Geochemistry” _builder_version=”4.16″ _module_preset=”default” box_shadow_style=”preset4″ box_shadow_color=”#c10000″ global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.16″ custom_padding=”21px|10px||10px|false|false” animation_style=”fade” global_colors_info=”{}”]<\/p>\n Humidity Cell Testing (HCT)<\/span><\/p>\n Since 1980, ACZ has been supporting the global mining industry\u2019s specialized needs, from baseline studies to operational water quality monitoring, plus static and kinetic testing for acid rock drainage prediction (ARD). ACZ Laboratories offers Humidity Cell Testing (HCT) via ASTM D5744-13 in a new state-of-the-art laboratory. HCT is designed to simulate in-situ weathering of waste rock and tailings in a controlled laboratory setting. ACZ\u2019s highly experienced staff, quality assurance program as well as state and national certifications (NELAP) ensure our clients\u2019 data is accurate, defensible, and reproducible. All analyses are performed in accordance with globally recognized standards (ISO 17025).
