Здравствуйте. Подскажите, пожалуйста перевод термина "as-discharged". Контекст: Since 1996, the chemical composition of the as-discharged tailings was monitored on a monthly basis. Samples of as-discharged tailings slurries were collected in the mill on a daily basis. https://www.sciencedirect.com/science/article/abs/pii/S08832...
