摘要： A phosphorus production method can include reducing feed containing phosphate ore and providing a silica ratio from 0.3 to 0.7 in a reaction chamber from 1250 to 1380 °C. Less than 20% of the phosphate remains in the residue. Another phosphorus production method includes continuously moving a reducing bed through the reaction chamber with the feed agglomerates substantially stable while in the reducing bed. Reaction chamber temperature can be from 1250 to 1380 °C. A phosphorus production system includes a barrier wall segmenting the reaction chamber into a reduction zone differentiated from a preheat zone. The bed floor is configured to move continuously from the preheat zone to the reduction zone during operation. A method for producing a reduction product includes exothermically oxidizing reduction/oxidation products in the reaction chamber, thereby adding heat to the reducing bed from the freeboard as a second heat source.

摘要： A process for recovering phosphorus from phosphoritic materials in a top submerged lance furnace or a fuming furnace is disclosed. The process employs a mixture of combustion agents to produce reducing conditions in the slag bath and post- combustion oxidising conditions in the headspace of the furnace. The process involves smelting a mixture of a phosphoritic material and a carbonaceous material in the furnace to produce a molten slag in the slag bath and phosphorus vapour in the headspace, wherein the post-combustion oxidising conditions in the headspace favours retention of ferrous oxides in the molten slag to minimise deportment of phosphorus to a ferro-phosphorus alloy; The phosphorus vapour in the headspace is subsequently oxidised to produce phosphorus pentoxide, which is subsequently passed from the headspace to a reactor to recover a phosphoric acid solution.

摘要： A process is disclosed for recovering elemental phosphorus from an aqueous sludge and converting the residue into non-hazardous waste. The sludge is separated into (1) a slurry of water containing suspended phosphorus and dirt particles and (2) coarse solids. A flocculating agent is added to the slurry to agglomerate the suspended phosphorus and dirt particles, which are recovered from the water and are heated to melt elemental phosphorus. A coalescing agent is added to coalesce the melted elemental phosphorus, which is separated from the dirt particles. The coarse solids are mixed with hot water to melt the phosphorus sludge in it, which is then separated from inert solids. The solids are heated to burn any residual elemental phosphorus. The separated molten phosphorus sludge is stirred with a solution of chromic acid to recover the phosphorus as a separate phase. A reducing agent is added to the remaining water and solids to reduce the Cr to Cr . Finally, an alkali is added to the water and solids to react the residual phosphorus and form phosphorous compounds. The reaction mass is filtered and the filter cake can be placed in a landfill as a non-hazardous waste.

摘要： Disclosed is a method of recovering elemental phosphorus from a sludge that contains water, dirt, and elemental phosphorus. In the first step, the sludge is melted. A mixture is formed of the melted sludge and about 0.5 to about 3 wt% of an oxidizing agent, based on the weight of said elemental phosphorus in the sludge, and about 75 to about 400 wt% water, based on the weight of the sludge. The mixture is stirred until a continuous elemental phosphorus phase forms. The purified phosphorus phase is separated from the mixture.

摘要： An apparatus and method for removal of cadmium can include a first reactor that is configured to calcine material containing phosphate and subsequently feed that calcined material to a cadmium removal vessel that is operated to remove cadmium from the calcined material. The cadmium removal vessel may be operated so that conditions in the vessel provide a reducing environment for removal of cadmium from the calcined material. The removed cadmium can be subsequently processed via heat exchange and filtration that is configured to remove a substantial amount, if not all, of the cadmium from a flow of material containing the removed cadmium prior to gas of this flow of material being output to the atmosphere. In some embodiments, a seeding agent may be added to the material flow containing the cadmium prior to, during, or after heat exchange to help facilitate filtration of the cadmium out of the flow.
