Heavy oil is considered as a multipurpose complex mineral, and the processing of heavy oils as a “complex problem”, aimed both at increasing the yield of light fractions and “transport” ability of oil, and at extracting metals from heavy asphaltene resinous fraction. The recovery of heavy metals (such as vanadium, nickel, titanium, iron, etc.) from heavy oil was performed by cavitation extraction technology with the use of light hydrocarbon solvents and chemical extractants, including a stage of extraction in an ultrasonic field with separation of insoluble fraction of asphaltenes in which a significant part of initial heavy metals and sulfur is concentrated, followed by re-extraction of metals and magnetic separation of metal aggregates.

Caustobiolites中的技术拟形关联及其提取方法

重油被认为是一种多用途的复杂矿物，重油的加工被视为“复杂的问题”，旨在提高轻质馏分的收率和油的“运输”能力，并旨在从重质沥青质树脂质馏分中提取金属。使用轻烃溶剂和化学萃取剂通过空化萃取技术从重油中回收重金属（例如钒，镍，钛，铁等），包括在超声场中进行分离的阶段首先将大部分初始重金属和硫集中的沥青质不溶级分浓缩，然后再萃取金属并进行磁分离金属聚集体。
